Aquarium and Pond Care with EcoBio-Block

Algae growth can be a serious problem for both indoor aquariums and outdoor ponds. In an outdoor pond, a limited amount of algae can lend your pond a natural appearance and it can also provide a healthy food source for your fish. If algae spreads too quickly, however, and if its growth is not controlled it can threaten the healthy balance you have worked so hard to maintain in your pond. To avoid having to deal with a sudden algae problem, take early and consistent steps to control and limit algae growth within your pond.

The Pros and Cons of Algae in Ponds

Algae are single-celled organisms that thrive in warm, nutrient-rich water. In an outdoor pond, algae are an essential part of the food chain. Algae subsist on the waste produced by your fish and, in turn, become a food source for your fish. In limited quantities, algae can enhance the appearance of your pond by giving it a more natural look but if it grows out of control algae can cover the surfaces in your pond with a green or brown slime. In addition to this slimy muck, algae can also turn your pond water an unsightly shade of green. This may reduce the clarity of your pond water and make it more difficult for you to view your fish. In addition to the aesthetic problems induced by its growth, algae can also deplete the oxygen supply in your pond water which will make it a stressful environment for your fish.

Factors that Contribute to Algae Growth

Like any aquatic plant, algae require nutrients to grow and if your pond provides an abundance of these nutrients you may experience a problem with algae. Organic matter and uneaten fish food settle at the bottom of your pond which will, over time, result in a build-up of ammonia and nitrate on which algae can feed. Direct sunlight is another contributing factor in the growth of algae so if your pond is not shaded by trees you may have trouble with algae. Though it can be harmful to your pond if too much algae is allowed to grow, most ponds experience a “bloom” of algae in the spring. In most cases, your pond will find its balance after a few weeks and return to its normal clarity.

Tips for Controlling Algae

Installing an adequate filtration system in your pond is an easy way to limit the growth of algae. Many pond filters utilize chemical filtration which helps to remove the wastes and toxins that would otherwise provide a food source for algae. Adding aquatic plants to your pond is another easy solution because plants will compete with algae for the same nutrients, thus limiting the potential for algae to grow and spread.  Introducing some floating plants like water lilies may also help to control algae growth by cooling the water and providing shade.

In addition to these measures, adding an EcoBio-Block Wave or nsM to your outdoor pond can be effective in clarifying the water and reducing algae growth. EcoBio-Blocks are made from natural zeolite and special cement that has been infused with special beneficial bacteria. Once the block has been installed in your pond it will release bacteria regularly which will work to break down organic waste into ammonia, then nitrites and then into nitrates. EcoBio-Block keeps water healthy which discourages the growth of algae. It also appears to encourage the growth of anaerobic bacteria, which changes nitrates (on which bacteria feed) to nitrogen gas. This product is a simple way to control algae and a great way to keep your pond water clean and clear with no extra effort required on your part.

cyano bactria infected water

One of the biggest challenges for aquarium owners is an outbreak of single celled organisms called cyanobacteria. They are casually referred to as blue-green algae because they are typically bluish green in color (although sometimes black or red) and aquatic; they are, in fact, microscopic bacteria that, when prolific, form into shiny sheets that look like algae.

Cyanobacteria also act like algae because they create their own food through photosynthesis. Given enough light and nutrients in the water, cyanobacteria can cause a bacterial bloom that can lead to major problems in the aquarium.

A cyanobacterial bloom may be free-floating greenish brown particles that make the water look hazy. The bacteria may also colonize into ugly films of slimy looking growth covering rocks and plants in the aquarium. Uncontrolled, a bacterial bloom can gather into foam or scum on the surface of the tank and give off a nasty rotten smell. At any rate, the proliferation of cyanobacteria is an indication that the nutrients that feed it – organic matter and waste products – are excessive in the water, which can only mean that the fish are in grave danger.

Cyanobacteria problems can be prevented with good fishkeeping conditions and attentive maintenance. In the event that a cyanobacterial bloom occurs, several steps can be taken, the first of which is to reduce the amount of light exposure in the tank. Because cyanobacteria thrive through photosynthesis, depriving them of light curtails their growth.

Together with reduced lighting, an effective way to fight cyanobacteria is consecutive water changes. Water changes up to 20% every three to four days will reduce the concentration of phosphates and waste material that feed the cyanobacteria. Test kits for nitrates and cyanobacteria are helpful in determining when healthy levels have been achieved. And to prevent future problems, it is best to maintain the aquarium with just the right number of fish, highly efficient filtration, and no over-feedings.

At times, though, cyanobacterial bloom can be unrelenting enough to defy light deprivation and water changes. Some fishkeepers resort to antibacterial chemicals, which could be equally detrimental to fishes and plants. A greener, more eco-friendly solution is the EcoBio-Block Family Products, originally designed and currently being used to degrade toxins and pollutants from lakes, streams, and reservoirs in many Asian countries.

EcoBio-Blocks, EcoBio-Rocks, EcoBio-Stones, and EcoBio-Pebbles are porous, mineral-rich volcanic stones from Japan. They are embedded with prolific beneficial bacteria (“bacillus subtilis natto”) that can actively multiply every half hour into colonies that degrade organic matter and nitrify waste products in the water. Because they degrade the organic matter that feeds cyanobacteria, the internet radio show Pet Fish Talk feels strongly that EcoBio-Block helped clear up their cyanobacteria problem.

Cyanobacteria cannot be totally eliminated from the aquarium. Overgrowth and its toxic consequences, however, can be prevented with optimum water conditions through diligent aquarium maintenance together with proven eco-friendly solutions like the EcoBio-Block products.
