Saltwater Aquarium Plants… Here’s What They’re About…

Article by Sam Weston

Saltwater aquarium plants add color and interest to your marine tanks and form part of any well thought out marine tank. But that’s not all they do. Macroalgae and marine plants will also make the ecosystem in your tank healthier. Macroalgae are particularly beneficial as they provide a natural form of filtration in the saltwater tank.

Saltwater aquarium plants take in nutrients from the water in order to carry out their biological functions and growth. This action reduces the accumulation of toxic nitrates and phosphates and other impurities in the water. When you use plants in your marine tank the idea is to reproduce your fish and other organism’s natural habitat. A tank that contains saltwater aquarium plants is likely to be a healthy one.

Here are some examples of saltwater aquarium plants that you can choose for your marine tank:

Halimeda or cactus algae are hardy saltwater aquarium plants and won’t be fed on vigorously by most marine fish. It is also non-invasive so it won’t damage nearby corals or invertebrates. It does need good light to grow in however as well as enough calcium for growth. Halimeda are sensitive to high nitrate and phosphate levels and don’t like to be pruned.

Penicillus or “shaving brush” are saltwater aquarium plants that do a great job at absorbing excess nutrients like nitrates and phosphates from the water. They are usually not fed on by most fish and invertebrates except sea urchins. Plant the pencillus in the substrate and make sure the area is well-lit. If you add an iron supplement and trace elements regularly your pencillus should thrive. Pencillus has a hard calcium carbonate skeleton like halimeda an coralline algae and will do well across a range of conditions.

What about macroalgae? Macroalgae are saltwater aquarium plants that come in a variety of different shapes and sizes. They are to be found in a range of colors – red, green, brown and blue. These saltwater aquarium plants are able to photosynthesize. This means they use a pigment called chlorophyll to make their own food for growth and other functions.

In general these saltwater aquarium plants get most of the nutrients they need from the water in the marine tank. These include nitrates and phosphates. This makes them good allies in keeping your tank clean. You will need moderate to strong light for the growth of macroalgae. The way to avoid macroalgae growing out of control is to control the environment in which it lives. This means the water chemistry and amount of available light.

So are there ‘bad’ saltwater aquarium plants? Certain kinds of algae can become problematic in a marine tank.

Bubble algae is one of the most common pest saltwater aquarium plants. Bubble algae forms green bubbles on any hard surface, for example live rock. It can occur in masses of bubbles or single or in small groups of big bubbles. The bubbles might be smooth or rough. Bubble algae look nice, BUT they aren’t!

These saltwater aquarium plants grow fast and can take over your tank. Once you discover it the best thing to do is remove it and keep it under control. It can damage other plant species. You can usually remove it by hand. When you do, try not to break the bubbles as this might cause it to spread.

You can try to introduce certain types of fish like the Sohal Tang or Red Sea/Indian Ocean Sailfin Tang (Acanthurus sohal) to eat bubble algae. The best means of control, however, seems to be the “Emerald Crab”. These crabs won’t damage your corals but will eat the bubble algae. It is a good idea to learn about other such interactions between saltwater aquarium plants and herbivores as they might save you time and trouble in the future.

The emerald crabs are a great idea for the reef aquarium where they won’t fight with other inhabitants. There are even coral farmers who use emerald crabs to control algae around their hard corals! So you can protect your saltwater aquarium plants by stocking some of these little helpers.

So what’s your next step? Now that you know a little bit about the good and the bad kinds of saltwater aquarium plants, it’s your job to make sure you learn more. Your local aquarist will be able to tell you more about which saltwater aquarium plants are most suitable for your tank, level of expertise and the other species you want to stock.

You can also do more research on the Word Wide Web, visit your local library or buy books on the subject. Don’t ever buy your saltwater aquarium plants on a whim because you like the way they look. Always make sure you know as much about their nutrient, environment and lighting needs as possible. That way you can avoid making mistakes that cost time and money or even threaten the health of your tank in the long term.

Do choose saltwater aquarium plants that you find attractive as this is part and parcel of keeping a marine tank but never let your desires cloud your common sense. Once you have all you plants set up you will be able to enjoy the animal plant interactions that are so much a part of the marine ecosystem. The purpose of any aquarium is to provide both the fish and you with hours of pleasure and enjoyment. A healthy tank is a happy tank so do take the time to do your research.

Saltwater aquarium plants are very beautiful to look at and interesting to grow so make sure that you take the time to enjoy the plants in your tank. Find out if it is possible to propagate any of these plants from, how to increase or decrease their growth and what nutrients they need to stay healthy. Never share plants between aquariums unless you know they are 100% disease free and always put the health of your tank at the top of your list of priorities! Have fun and enjoy your saltwater aquarium plants!

Saltwater Aquariums, Setup, Maintenance, and Overview

This article is simply aimed to help beginning hobbyists that wish to set up a saltwater aquarium and also to help create a basic and essential knowledge base. Beginners should not be intimidated by anything they have heard about saltwater aquariums pertaining to its difficulty and complexity. This hobby is not difficult. One simply must have enough knowledge to effectively maintain a thriving aquarium.

First, you simply must think about what you would like to do and create a plan. Decide on what size aquarium you would like. In general when deciding on the size for saltwater aquariums, the bigger the better. A beginner should probably not choose an aquarium less than 30 gallons. For a delicate ecosystem, any imbalance created, such as an increase in nitrates due to a dead animal, would be diluted over a greater volume of water causing fewer dangers in a larger system. Problems can be solved much more easily within a larger aquarium.

Take a look at some saltwater animals. You can always check out a local store or simply go online. Decide what you would like to accomplish with your new aquarium. You may want to go for a tank full of large predator animals such as lionfish and groupers, or maybe you would like a small peaceful community. Also, deciding whether you would like to include corals or other photosynthetic animals will change the costs as well as the types of animals that you will be able to keep.

When considering the equipment needed to start a saltwater aquarium, some items are variable while others cannot be avoided. The importance of each of these items will be discussed later. Here is a list of what should be considered:

         -A sturdy aquarium stand. Look for a stand that is in great condition and appears capable of holding the aquarium’s weight

         -A proper size protein skimmer is highly recommended. This is an essential part of a marine aquarium. Protein skimmers filter out organic wastes. Micro bubbles produced will bind to dissolved organic wastes in the water and rise and collect in a scum cup. This filtration system is no doubt a must in a marine aquarium.

         -A proper size powerhead to maintain water flow. A powerhead is simply an in tank pump that creates current. You may need a higher flow model or more than one powerhead to achieve a proper amount of water movement in your aquarium depending on its size.

         -A proper wattage heater will be necessary when room temperature is not high enough to maintain the correct temperature in the aquarium

         -Mechanical filters can be used but are not completely necessary. These will simply keep the aquarium clean and make less effort for you. This is the standard filter you would hang on any aquarium and these come in a variety of shapes and sizes.

         -The proper lighting for your aquarium will be determined by what you plan to keep in your aquarium. If you do not wish to keep corals, simple inexpensive fluorescent tube lighting will be sufficient. These lights are those that typically are included in tank packages. Soft corals will require stronger and more expensive compact fluorescent lighting and stony corals will require yet stronger and more expensive metal halide lighting.

         -A hydrometer or refractrometer will allow you to check the levels of salt in the water. Refractrometers are significantly more expensive than hydrometers but are typically much more accurate.

         -Chemical test strips will be needed to monitor your water chemistry. These are available in multi test strips to make this convenient. The most important tests to look for are nitrate, nitrite and ammonia.

Now, when considering setting up your aquarium, many one time items must be purchased in order to begin. Some are variable based on whether or not you have chosen to raise corals in your aquarium. Here is a list of what must be considered.

         -Live Sand is highly recommended when aiming to start a reef system. A little less than a pound per gallon would be sufficient.

         -Live Rock is also highly recommended for a reef system and can also be used in a fish only system. The amount of live rock is variable based on how large it is compared to it density as well as how much you would like to purchase based on how you would like the aquarium to appear. However, a nicely stocked system may include around a pound per gallon. “Live” is simply a termed used to describe sand and rock that is filled with tiny organisms and bacteria colonies. Detritivores found in live sand such as mysis shrimp, stomatella snails and bristleworms are all extremely useful is keeping a tank clean and healthy. Small organisms like copepods are also very helpful and also will serve as food for many saltwater fish and invertebrates.

         -Regular saltwater aquarium sand should be purchased. There a few different types and grain sizes of sand that can be purchased. Choose based on the animals you intend to keep. For example, small burrowing bottom dwellers will prefer small grain sand. In most aquarium setups, fine aragonite sand will work very well. However, a good guideline would be 1 ½ to 2 pounds of sand per gallon. Aim for around 4” of sand.

         -The saltwater itself can purchased if you have a provider that sells premixed saltwater. However, if it does not, you may have to buy enough salt mix in order to make the amount of saltwater you will need. A Reverse Osmosis (RO) system may be a consideration as you will not want to continue purchasing distilled or RO water in order to top off your aquarium. These systems are typically installed underneath and sink and home models will allow for a spigot above the sink to draw the water. RO water is also drinkable. You cannot make saltwater with tap water even if you use a water conditioner. You will need to make your saltwater with RO or distilled water. You will also need to top off due to evaporation with RO or distilled water. You may be able to purchase RO water from your provider but although a larger investment, an RO system at home may save you a lot of money in the long run.

Ok now to start your aquarium. After you have taken everything home you will need to set up your aquarium that day if you have purchased live sand or live rock. The actual setup of the aquarium is quite simple.

You will want to place the live sand in piles as it comes out of the bag and not spread it out. Next, add all of your dry sand. Dry sand should be rinsed before added as it may contain a high amount of dust. This can be done by simply adding water to a bucket with the sand and mixing and pouring out the water when finished. In order to keep a more appealing look, the sand can be angled to be lower in the front and deeper in the back in order to keep a minimal amount against the front and visible part of the aquarium. Add live rock next and stack in a secure fashion. Dig rock at the base into the sand in order to prevent any toppling. Fill the aquarium after adding your rock. If you need to mix water, do this beforehand. Place a plate at the bottom of aquarium and poor water onto it to avoid stirring all the sand you just placed. You can then attach all equipment to the tank. You may want to allow any sand to settle before starting up your filter or protein skimmer.

After everything has settled you may start up all equipment. The aquarium may take on a very foggy look for the first few days. This is normal and will clear. It is advisable that you wait at least a month before adding anything to your new aquarium. This will allow a full nitrogen cycle in the water and prevent any chemical imbalances from killing any of your animals. Also, when live rock is moved and placed in a new environment, there will be some die-off of the microorganisms, bacteria and other little critters. That can easily cause a spike in ammonia, nitrates or nitrites.

After you have had the system running for about a month, all chemical levels should be tested before adding any animals. As a general rule for saltwater, nitrate, nitrite and ammonia levels should all be relatively close to 0 ppm. Salt levels or specific gravity, should be around 1.022-1.024. Temperature should remain around 78 degrees.

Now when you add animals, a good clean up crew is a great start and generally inexpensive and includes animals that are indicators of problems. Typically these will be sold with a variety of animals such as small hermit crabs, snails, serpent stars, and many others. Always ask for detritivores. These animals are extremely beneficial to your aquarium and will ensure its success. After you have allowed these animals to acclimate the environment and you see no problems, you can then add fish and more expensive species. Always research compatibility of saltwater creatures as there are many potential conflicts.

Helpful tips

Maintaining your aquarium after it is up and running:

-The most important part of maintenance is keeping up on regular water changes and topping off the aquarium. You should top off the aquarium to a designated point frequently with RO water (not salt) to keep the proper water level and salt content. A 20% water change of the aquarium should be made about every month (with mixed salt water to proper content level). Siphon the water out but do not siphon sand in a saltwater aquarium. Gravel vacuums are designed for freshwater rocks and one should never disturb the sand bed of a saltwater aquarium too much.

-Always make sure that protein skimmer scum cups are emptied regularly and that the skimmer is functioning properly. This is an important piece of equipment for a saltwater aquarium.

-Mechanical filters should also be cleaned and filters changed regularly

-A good scraper should be purchased to clean the glass of the aquarium

-Saltwater tanks with corals should run lights equivalent to what a typical day would be (10-12 hours), also if possible, turn lights on around the room with the aquarium in order to acclimate them to the light. Corals and fish react the way you would if someone flicked the light on while you were sleeping too!

-Watch for nuisance algae or bacteria. These are indicators that something has chemical is out of its range in the aquarium. This can be caused by a dirty skimmer or filter, dead animals, running lights too long, overfeeding, a lack of water changes as well as many other causes.

Adding Animals:

-Saltwater animals are very sensitive to changes in their environment and can be easily stressed which can lead to their death quite quickly.

-When you bring home a new addition, always float the bag in the water for at least 10 minutes to equalized temperature.

-The bag can then be cut open, and the top rolled down to make it float or clipped to the side of the aquarium.

-Water should be poured from the aquarium into the bag in small amounts every 5-10 minutes until the bag is full. Aim to make it take about an hour to fill the bag.

-Even more sensitive animals such as starfish should take extra long to complete this process. Aim for around 2 hours for those animals.

-Net an animal out of the bag and place into the aquarium after the process is complete. You should not add the bag’s water to your aquarium as the water could have diseases in it that your aquarium is not immune to. If you cannot net the animal, add as little of the bag’s water as possible. Simply pour the bag’s water out in the sink.

Acceptable Chemical Levels

-If maintaining a fish only system a small amount of nitrate, nitrite and phosphate can be acceptable. Corals and invertebrates demand a much more stable environment. Phosphates and calcium are generally not on multi-purpose test strips but also do not need testing very often. Advanced aquarists may choose stony corals and thus must monitor calcium and alkalinity.

Saltwater Aquarium Lighting Guide

Lighting your saltwater aquarium can be one of the most difficult tasks for new hobbyists. Many people planning their first saltwater aquarium suffer from analysis paralysis. They get hung up trying to figure out what light fixture will work best for their aquarium. They consult their local fish store and then online forums, but are oftentimes lead down the wrong path.

In 2010, there are really only a few lighting types you should consider. If you plan to keep just fish, also called a fish only aquarium you will be fine with the standard stock lighting that comes with your aquarium. If you plan to keep a reef tank with living coral, then consider the following options.

Power Compact was definitely the most popular lighting solution from 2000 to 2005. It provided a substantial upgrade from the normal output lighting. It is still featured on many tanks today, but there are better and more cost effective options.

VHO or Very High Output lighting.

Do not even consider purchasing this type of light. The technology is outdated. Parts and replacement light bulbs are becoming more difficult to find.

Metal Halide Lighting is still a very popular option. It provides an attractive shimmering effect that allows you to grow almost any type coral. The disadvantages of Metal Halide lights are the amount of energy required to run the fixture and the amount of heat they produce. These lights can be expensive to run ten or more hours per day and you may have to purchase a chiller to keep your aquarium cool if you live in a warmer climate. Metal Halide bulbs should be replaced every six to twelve months.

T5 Lighting has quickly become the top choice for most saltwater aquarists.

The bulbs can be as intense as Metal Halide, but they only use half the energy. They also produce less heat and each bulb needs to be replaced once per year. Another major advantage is you are able to control the color of the light spectrum because you have multiple bulbs that can be replaced to make your aquarium bluer or whiter.

Finally, you have LED Lighting. In 2010, this technology is still too expensive for the average hobbyist. It provides the power and shimmer of metal halide without the heat, and the ability to control the color of bulbs like T5 Lighting. In the next ten years, LED lighting will be the standard in the saltwater aquarium hobby.
