Aquarium and Pond Care with EcoBio-Block

Nothing is quite so devastating to an aquarium hobbyist than to spend hours arranging and cultivating a tank full of live plants just to have them eaten by the tank inhabitants. While many species of fish tend to nibble on aquarium plants, most do not actually eat them. There are some species, however, that are notorious plant-eaters and are capable of decimating an entire planted tank in a matter of days. To avoid having all your hard work be for nothing, be careful about which fish you select to stock your planted tank.

Fish to Avoid in Planted Tanks

Silver dollar fish are one of the species most well-known for eating aquarium plants. Though many fish are likely to pick at algae growths or bits of sunken fish food on the leaves of aquarium plants, silver dollar fish will actually consume the plants themselves. These fish are voracious eaters when it comes to vegetable matter and they can work their way through an entire planted tank in just a few days. Some species of cichlid have also been known to eat aquarium plants, but these fish are more likely to dig in the substrate thus uprooting aquarium plants. While being temporarily uprooted may not kill the plants in your tank, it can inhibit their growth. Gouramis have also been known to engage in digging behavior which can affect the health and growth of live plants in an aquarium.

Recommended Species of Fish

When it comes to selecting the fish for your planted tank you cannot go wrong with most species of community fish. Community species of fish are peaceful not only toward other fish, but they do not tend to disturb aquarium plants or other tank decorations either. Some of the best small species of fish for planted tanks include livebearers, tetras, barbs and corydoras catfish. If you prefer slightly larger fish, dwarf gouramis and discus fish are recommended for planted tanks. To be sure that your plants are safe, it is wise to do some basic research on the species of fish you intend to purchase before you bring them home – check to be sure the conditions in your tank are right for that particular species and determine whether they are likely to eat your aquarium plants.

Tips for Maintaining Planted Tanks

To prevent your fish from turning to your aquarium plants for food, provide them with plenty of fresh vegetables. Fish enjoy blanched vegetables like peas, broccoli, spinach and zucchini and all of these foods are very high in nutrient content. Another way to keep your aquarium plants healthy and thriving is to introduce an EcoBio-Planter into your tank. EcoBio-Planters are made from natural zeolite and infused with beneficial bacteria. Once these bacteria form a colony in your tank they will begin breaking down built-up wastes and will help to maintain the nitrogen cycle, thus keeping the water in your tank clean and clear. EcoBio-Planters are conveniently shaped to accommodate small rooted plants and they are a great way to decorate your tank while still keeping up a natural appearance.

Algae growth is a nuisance that most aquarium hobbyists have trouble with at one time or another. Excessive algae growth is something that can creep up slowly or it may suddenly take over your tank in the form of an algae bloom. If you hope to control algae growth in your tank, you first need to cultivate an understanding of the different types of aquarium algae. Once you know the basics you will be able to identify the algae growing in your tank and you will then be able to take the proper steps to control it.

Types of Algae in the Aquarium

from left: brown algae, green algae, and thread algae

Brown Algae = This is the most common type of aquarium algae and it is likely to be found in new tanks as well as aquariums with low lighting. Also called diatoms, brown algae presents in the shape of soft clumps that form on aquarium walls and décor. This type of algae can be easily removed by hand and it can be controlled through the introduction of live plants or algae eaters like aquarium snails and Otocinclus catfish.

Green Algae = This type of algae usually presents as green water in the aquarium and it is often a result of poor water quality. Green algae, also called an algae bloom, grows quickly in tanks that have too much light and in new tanks that haven’t been cycled correctly. Because it typically forms a film on tank walls and décor, green algae can easily be wiped off and it usually goes away on its own once the tank conditions have stabilized.

Cyanobacteria = Often called blue/green algae, cyanobacteria are actually microscopic organisms that spread throughout the tank in slimy blue/green sheets. This type of algae can be removed easily by hand and its growth should be controlled or it may result in the death of fish and aquarium plants.

Green Spot Algae = Presenting in the form of hard green spots on tank walls and plants, this type of algae is one of the most stubborn. Green spot algae is typically found in tanks exposed to too much light and tanks with low CO₂ and Phosphate levels. The best way to remove this type of algae is by scraping it away with a razor blade – few species of algae eaters are successful in removing green spot algae growths.

Red/Brush Algae = Brush algae, also called red algae, tends to collect on slow-growing aquarium plants. This type of algae can grow in either acidic or alkaline conditions and it is difficult to remove by hand. Siamese algae eaters are one of the only known species that are effective in controlling this type of algae growth.

Thread Algae = This type of algae takes the form of long threads which grow up to 30cm long and hang on to leaf edges. Thread algae is likely to grow in tanks that are low in iron and it can easily be removed by twirling the growths around a toothbrush. This type of algae can be controlled through the introduction of Siamese algae eaters into the tank.

Tips for Controlling Aquarium Algae

In order to keep algae levels low in your aquarium you need to limit the nutrients available and make the tank environment less ideal for algae growth. Keeping your tank clean through routine water changes and by limiting the amount of food you give your fish are two simple ways to limit the nutrients available to algae. Live aquarium plants are another great solution because plants will compete with algae for nutrients, thus limiting the ability of algae to grow. Keeping your tank out of direct sunlight and limiting your use of artificial light to 10 or 12 hours a day are the best ways to make your tank environment less likely to encourage algae growth.

Another simple way to keep your tank clean and clear is to introduce an EcoBio-Stone. An EcoBio-Stone is made of porous volcanic rock and is infused with unique beneficial bacteria. Once they have been introduced into your tank, these bacteria will multiply and help to maintain the nitrogen cycle. The nitrogen cycle is simply the process through which wastes are broken down and the resulting ammonia is converted into nitrates. Once you install an EcoBio-Stone in your tank, the beneficial bacteria will take over, helping to keep your tank water clean and clear. A clean aquarium is less likely to experience excess algae growth and it will be a healthier environment for your fish.

Many inexperienced aquarium hobbyists make the mistake of selecting the fish for their planted tank on a whim. They simply walk into the pet store, purchase a few species that they like and take them home. If you follow this method you may find that after a few days in your tank, or even a few hours, your fish will have devoured all of the plants you worked so hard to raise. In order to avoid this kind of disaster you should perform some basic research to determine which species of aquarium fish are not likely to eat the plants in your tank.

Types of Fish That Eat Aquarium Plants

While many species of aquarium fish are likely to nibble on the plants in your aquarium, some are capable of decimating your entire planted aquarium in a matter of hours. Silver dollar fish, for example, are particularly notorious plant eaters. Other species like mollies and swordtails may nibble at your plants but will rarely do any major damage. Though they may not actually eat your aquarium plants, some larger species like gouramis and cichlids may uproot and break apart the plants in your tank and algae eaters may chew holes in them.

Species of Fish Safe for Planted Tanks

If you have taken the time to cultivate a planted tank you should also make the effort to ensure that the fish you add to your tank will not destroy all of your hard work. Most small, community species of fish pose no threat to aquarium plants. Barbs, tetras, danios and guppies are all unlikely to do anything more than pick flakes of food from the leaves of aquarium plants. Even some of the slightly larger species like discus, killifish and dwarf gouramis are safe for planted tanks. Other species that are recommended for planted tanks include corydoras catfish, platties, gobies, minnows and betta fish.

Tips for Maintaining a Planted Tank

Healthy Planted Tank

There are many benefits to cultivating live aquarium plants in your tank. Not only do live plants enhance the aesthetic appeal of your tank but they can also increase the oxygen level and help filter out harmful toxins. In order to keep your aquarium plants healthy you need to provide a healthy aquarium environment. To create this type of environment you will need adequate light, nutrition and filtration.

In addition to these three things there is something else you can do to keep your tank a clean, healthy environment for your plants and fish. Introduce an EcoBio-Planter to your mid-size aquarium as a simple way to remove odors and clarify your tank water (for larger tanks, simply add another planter or a stone). EcoBio-Planters are made from natural zeolite and crushed stone which has been infused with beneficial bacteria. Once introduced to your tank, these bacteria will multiply and establish a colony that will then work to break down wastes, remove odors and speed up the nitrogen cycle. EcoBio-Planter is also terrific for your plants. Simply place a small root ball in the opening and the plant will grow and thrive, greatly adding to the beauty of your planted aquarium.

Aquarium Substrate

When it comes to setting up your aquarium for the first time one of the most important decisions you can make is what type of substrate to use. Many first-time aquarium hobbyists do not even realize that they have a choice beyond natural or colored gravel. While gravel serves its purpose well as an aquarium substrate, there are other options and some of these options have additional benefits for your tank. If you plan to keep live aquarium plants in your tank it is especially important for you to choose a substrate wisely.

Different Types of Substrates

Gravel : As one of the most readily available types of substrate, gravel is also one of the most popular. Not only is gravel easy to find and inexpensive to purchase but it comes in a variety of shapes and sizes which makes it a great option for hobbyists who want to customize their tank. Another benefit of gravel substrate is that it can be relatively easy to clean – you can simply remove it from the tank and rinse it in warm tap water until the water runs clear. Gravel can also serve as a base for the growth of beneficial bacteria but it does not provide any nutrients to support the growth of live aquarium plants.

Sand: Sea sand is not recommended for freshwater aquariums but it is popular for use in marine aquariums. This type of sand often contains impurities which can cloud the water and it may also contain pieces of shell or coral that can raise the pH in the tank. Play sand, however, makes an excellent substrate for freshwater aquariums because it has been sterilized and requires less-frequent cleaning than aquarium gravel. Aragonite is another popular type of sand substrate that is useful in buffering pH levels in saltwater aquariums.

Vermiculate: This substance is a substrate composed of the minerals aluminum, iron and magnesium. This substrate has a high cation exchange rate which helps aquarium plants to utilize nutrients. Vermiculate is an excellent substrate for planted tanks because it releases nutrients over a long period of time which negates the use of fertilizers. The best way to use this substrate is as a lower layer on the bottom of the tank covered or mixed with a layer of gravel.

Laterite: Laterite is a type of porous clay, often reddish in color, which can be used as a substrate in freshwater aquariums. This type of substrate attracts and holds nutrients, storing them until they can be utilized by aquarium plants. Like vermiculate, this substrate is best used as a lower layer in the home aquarium, covered by a layer of sand or gravel.

Tips for Using Aquarium Substrate

Do not think you need to limit yourself to one particular type of substrate. If you have a planted tank it is wise to combine several types of substrate, like vermiculate and laterite, with gravel or another substrate in order to provide the necessary nutrients. In conjunction with the right substrate, introducing an EcoBio-Stone is a great way to keep your tank clean and healthy. EcoBio-Block products are made from porous volcanic cement that has been infused with beneficial bacteria. Once introduced into your tank, these bacteria multiply and help to keep your tank water clear and odor-free which results in less maintenance on your part and a healthier environment for your fish.

About 1/4" size snail on aquarium plant leaf

While aquarium snails may help to keep the algae in your aquarium under control, they have a tendency to reproduce quickly. A few small snails can turn into dozens in a matter of days and, before you know it, your entire aquarium could be overtaken. In most cases, aquarium hobbyists introduce snails into their aquariums unknowingly and do not notice the snails until it is too late. There are steps you can take, however, to prevent this from happening to you and there are ways to deal with it if it does.

How Snails Get into the Aquarium

Purchasing live aquarium plants at the pet store and adding them directly to your tank is the number one way snails are introduced into the home aquarium. While some pet stores now sell guaranteed snail-free plants in plastic containers, most pet stores only offer them straight out of their stock tanks. Even if your store does offer snail-free plants, they may cost several dollars more than the same plant from a stock tank.

Once you get your aquarium plants home, rinse them with warm water from the tap. Go over each leaf and remove any snails you happen to find. As an extra precaution, you can also soak the plants for 10 minutes in warm salt water. If you choose this method, be sure to rinse the plants well with fresh water before adding them to your tank.

How to Control a Snail Infestation

If you find yourself with a growing population of snails in your tank, do not panic. If you catch the problem before it gets out of control you may be able to remedy it with a few simple steps. Before you go to bed at night, blanch a piece of lettuce in hot water and drop it into the tank. In the morning you will find that snails have swarmed to the piece of lettuce and you can simply remove it from the tank, along with the snails feeding on it, and discard it.

While chemical remedies for snail control are available, they may do more harm than good in your aquarium. These remedies are designed to kill invertebrates like snails but they may also decimate your population of beneficial bacteria which could lead to other problems like cloudy water and algae blooms. If the snails in your tank become too numerous to control, however, you may need to resort to drastic measures such as performing a major tank cleaning.

Move your fish into a temporary tank filled with water from the main tank – you may also wish to set aside a few buckets of water from the main tank to use in refilling the aquarium. Empty the tank, clean the walls and soak all tank décor in warm saltwater for at least thirty minutes. Remove the gravel and either soak it in salt water or boil it on the stove. Check your live plants for snails, remove any you find and soak the plants in warm salt water for ten minutes. Do not forget to rinse out your filter as well.

Thoroughly rinse everything you soaked in salt water then reassemble your tank and refill it with as much of the original tank water as you can. This will help to speed up the nitrogen cycle and should also help to prevent algae blooms. In order to quickly reestablish a colony of beneficial bacteria in your tank you might consider installing an EcoBio-Stone. These products are made from porous volcanic rock and are infused with beneficial bacteria ready to multiply after being added to your tank. EcoBio-Stones help to speed up the nitrogen cycle while removing odors and clearing up your aquarium water. Once your tank has cycled, leave the stone in place to keep your aquarium water clean and clear.
