Surface Aeration For Pond Algae Control
Surface Aeration All ponds and lakes will benefit from aeration. Pond aeration is just like adding air to an aquarium. With air, the aquarium stays fairly clean. Shut off the air and it starts to turn green. Adding oxygen to a pond helps aerobic bacteria thrive. They are the lifeblood of a healthy pond as aerobic bacteria are much more effective than anaerobic bacteria at breaking down organic matter and excess nutrients. Bottom diffused aeration brings water from the bottom of the pond to the surface where it comes in contact with sunlight and wind, which add viable oxygen. This water then goes back down to the bottom where the aerobic bacteria can start to eat the black organic matter and muck on the bottom. Surface aerators – effective on ponds with higher fish stocking rates. They can add supplemental oxygen needed to keep fish alive in the warmer summer months. They’re not as effective as bottom diffused aeration in circulating the water from top to bottom and eliminating stratification unless the pond is fairly shallow (< 8 feet). Fountains – they look great but are not really designed for aeration. They can help, especially in shallow ponds but do not add as much oxygen as a surface aerator or bottom diffused aerator. The existence of algae in you pond may be a fact of life, but it is good to know that there are ways to prevent excessive growth of it and there are ways to control it with some patience and the right tools. Outdoor Water Solutions manufactures a wide range of pond and lake products for algae control. You can learn more at www.Outdoorwatersolutions.com or by calling 1-866-471-1614 for a free catalog.

Pond Algae Control
Pond Algae Control Once you have a problem with pond algae, there are a couple of options for controlling the situation. The most common is to add a copper based algaecide, either in dry or liquid form, to kill the visible algae. You want to avoid not killing too much algae at one time because it will take most of the available oxygen out of the water and you may end up with a fish kill. Most companies recommend treating one-third of your pond at a time. Algaecides can be effective at controlling what you can see, but this does not address the bigger problem. As a result the algae problem will come back time and again. Killing the algae can also contribute to more and more excess organic matter as when it dies. It will sink to the bottom, adding yet another layer of rich, black organic matter that feeds more algae. Grass carp sometimes eat algae, but it is not common. They have been seen eating plants coated with algae, but their mouth and gills are not positioned to eat algae effectively. Although grass carp can be used to control some aquatic weeds, they should not be stocked to control algae. In fact, grass carp can add to a nutrient problem and cause algae to multiply if they are no longer eating aquatic weeds efficiently. The existence of algae in you pond may be a fact of life, but it is good to know that there are ways to prevent excessive growth of it and there are ways to control it with some patience and the right tools.
