subject: How to Control Pond Algae With a Waterfall [print this page] There are many chemical algaecides on the market designed to control algae growth, but there are some risks associated with their use. Most algaecides use copper, which carries two main disadvantages. One, many algae have become resistant to the chemical. Two, the copper in the algaecide is harmful to beneficial bacteria.
Beneficial bacteria is the way that nature uses to keep ponds cleaner. Sludge has a tendency to form at the bottom of ponds, and it is the beneficial bacteria that helps to break down this organic material and keep it from accumulating. The more organic material that is allowed to accumulate, the more algae is encouraged to grow.
So while using chemical algaecides has its disadvantages, there are a couple of ecologically-friendly methods that you can combine to effectively control algae growth.
Pond aeration is the primary natural way to control algae growth. Pond aeration involves making sure there is plenty of oxygen in the water. There are a few methods to accomplish this. One way is to install an aeration kit that uses a compressor and diffuser to pump air into the pond.
Another method is to incorporate a waterfall feature that is effective at introducing oxygen into the water. Waterfalls add considerably to the beauty of ponds. The sound of the splashing water is also soothing to the ears and is conducive to relaxation.
You would need to build the waterfall above the pond, and there are number of building materials and options you can use to accomplish this, from boulders to cinder blocks. You then need a waterfall pump and tubing to recirculate the water.
