The best pond water algae controllers are actually not things you can do at all. The best pond water algae controllers are the natural operations of a healthy pond eco system. That said, there are a few things you can do, once you have exhausted your natural options.
Finding the proper balance of water, fish, plants, aeration, algae and bacteria is the best of all pond water algae controllers. Healthy pond eco systems are begun by fish and their waste. When fish excrete their waste, it joins with natural materials in the water like leaves and breaks down. Then they sink to the bottom of the pond where bacteria begin to transform them into one chemical after another until they have broken down into a chemical which can be used by plants and algae in the pond as a source of nutrients. Having enough plants will prevent algae from taking over the pond’s eco system by using those nutrients before algae is able to. The algae and some of those plants then become food sources for the fish and the cycle begins again. If there are not enough plants or there is not enough oxygen in the water, algae will begin to overtake the pond. This is why having a harmonious balance in the pond is the best of all pond water algae controllers.
If, for some reason, algae has taken over your pond, you can try to remedy the situation using natural pond water algae controllers. Some of the things you can do are as follows. You can remove some of the fish from the pond. Although the fish are using the algae as a food source, they are also eliminating more waste with every moment, which then induces the bacteria to begin the breakdown of chemicals in the water, creating more nutrient which will be used by algae to reproduce. You can add more plants. This will work, but will not work quickly. By introducing more plants, you are giving the algae competition. The plants will begin to feed on the nutrients and in time, they will starve out the algae. You can also provide better aeration. This will get the water moving and will assist the breakdown of the algae and make the fish healthier, which will encourage them to eat more algae. The truth of this is that you will likely need to combine your efforts and do all three to provide the best pond water algae controllers.
There are several chemicals which can be used available on the retail market. These take many different forms, but all seek to accomplish the same thing, the elimination of algae. These are basically animal safe herbicides which will kill the algae in your pond. The problem with them is that they will need to be used on a continual basis to maintain an algae free environment. Once you stop using them the natural process of the pond’s ecological system will take over and the algae will begin to feed on the water’s nutrients again and will likely overtake the pond again as well.
Ultimately, the best pond water algae controllers are the balances between all the elements of your pond.
