Aquarium and Pond Care with EcoBio-Block

Once you have successfully built and set up your outdoor pond you may think that the hard part is over. While building your pond may indeed be the most difficult part of the process, you should also put a considerable amount of effort toward selecting the fish for your pond. You cannot simply go to the pet store and purchase a dozen feeder goldfish and expect them to thrive in your pond. There are only a few types of fish that are suited to living in outdoor ponds and each variety has certain requirements. Before you purchase the fish for your pond, perform some basic research to decide which type of pond fish is best for you and for your pond size.

Types of Pond Fish

Colorful koi

When it comes to outdoor ponds, koi are the most well-known species of ornamental fish used for stock. Koi come in a variety of shapes and colors including black, gold, red and orange. These fish look similar to goldfish but grow much larger and exhibit a wider variety of shapes in their fins and bodies. Because they grow to be quite large, koi require a pond capacity of at least 1000 gallons in order to thrive. These fish also require a variegated diet including fresh vegetables, fruit and specially formulated koi foods.

Goldfish come in a variety of shapes and colors which makes them a popular choice as a pond fish. Some of the most popular varieties of goldfish include Comets, Shubunkins and Orandas. Comets come in red, orange and white varieties – the calico varieties are called Shubunkin Comets. Orandas are a type of fancy goldfish known for the prominent hood that develops on top of its head.  In general, goldfish are a hearty species which does well in ponds with adequate filtration and aeration. Most goldfish prefer peaceful or slow-moving water and require a pond capacity of 250 gallons or more to thrive.

Precautions to Take with Pond Fish

Just as you should exercise caution when stocking your home aquarium, be careful when selecting the fish for your pond. Some species can grow very large or may become aggressive around other species. By doing some research before you purchase your pond fish you can prevent a disaster from happening later. Comets, for example, can be aggressive and should not be mixed with most other types of pond fish aside from koi. Goldfish and Orandas are generally peaceful species that can get along with a variety of species.

Tips for Keeping your Pond Healthy

A healthy pond requires routine maintenance in order to keep water quality high. Because goldfish and other pond fish are notoriously high producers of waste, adequate filtration is key to maintaining water quality. To give your pond a boost, consider installing one or more EcoBio-Block Waves. These blocks are infused with beneficial bacteria that multiply naturally to establish a colony in your pond. Once established, this colony of beneficial bacteria will help to break down organic waste products, remove odors and clarify cloudy pond water. While you should still maintain proper filtration and execute regular maintenance procedures, an EcoBio-Block Wave can help to keep your pond clean and healthy for your fish.

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.

Aquarium with Green Algae

Of all the irritating and unpleasant things that can happen to an aquarist, nothing is more likely to ruin his disposition and destroy his faith in the essentially benign purposes of nature than green water, particularly when it occurs, as it usually does, in a tank he is especially proud of or for some reason wants to watch closely.

The writer recalls vividly his own initial experience with this condition. He observed one morning that the water in his prize aquarium had lost its usual transparency. The next day it had a slightly green tinge. By the end of the week the contents of the tank had completely disappeared in a fog of pea soup, which the strongest light would not pierce. Hoping the condition was temporary and would clear itself up, he postponed doing anything about it, as the tank was a large one and cleaning it out would be no small job.

Finally deciding that further waiting was hopeless, he drew off all the water he could without removing about a hundred and fifty fish and replaced it with clear water. The improvement that resulted lasted only a few hours, and three days later the condition was worse than ever.

On the advice of more experienced friends the light was then cut down. The only result, after forty-eight hours, was to bring the fish to the surface gasping for air. Salt was added, likewise on the advice of friends. Effect-none. Other suggested remedies were tried without any improvement whatever, and finally the tank had to be cleaned out completely, washed, replanted and gotten off to a new start.

Following this experience an investigation was made which disclosed the following interesting facts:
Water everywhere in indoor aquariums as well as outdoor ponds, etc., is constantly receiving air borne spores of algae, yeasts, molds and other bacteria. When the water contains appreciable percentages of dissolved or suspended organic matter, the spores develop into bacteria, which break down this matter into its component salts. These salts are the food of plants, and when there is sufficient actively growing plant life in the aquarium the salts are absorbed by the plants practically as fast as they are formed. Under these conditions an aquarium is “balanced” and the water remains sweet and clear indefinitely.

When, however, the salts referred to are formed faster than the plants can absorb them, the algae spores (which in effect are microscopic plant seeds) find a foothold and tiny microscopic plants which swim about in the water develop in prodigious numbers. These algae take up the excess salts and keep the water sweet, but unfortunately they also create an unsightly appearance. Moreover they compete with the higher plants in the aquarium, robbing them of both food and light. In time the higher plants will succumb, leaving the algae in full possession.

It will be seen therefore that the development of green water arises in the first place from an unbalanced condition in the aquarium. The decay and dissolution of an undue quantity of uneaten food, dead snails, fish, plant leaves, excrement, etc., leads to a high bacterial content (indicated by cloudy or ill smelling water) which produces more food than can be consumed by the plant life present in the tank. The algae step in and the tank becomes green.

Cutting down the light kills the algae, removing the effect without touching the cause. This is true of any other remedy which merely kills the algae. The sudden death and rapid decomposition of a quantity of algae may foul the tank and kill the fish. The only logical, safe and permanent remedy for green water is to reduce the amount of decomposing organic matter in the tank or increase the number of plants. This means:

1. Find out whether the excess is caused by too many fish.
2. If not, watch your feeding and siphon off the bottom dirt more frequently.

Close attention and careful monitoring of your tank conditions should keep your aquarium clear and algae free. Products that increase beneficial bacteria in your tank, like the EcoBio-Block will help to keep your tank water “balanced” for 1.5 to 2 years and are added protection against “algae bloom”.
