Coptrol and Hydroponics

How to use Coptrol in hydroponic systems

Controlling algae in a hydroponic system can be difficult.

When algae are present in a system:

They use up nutrients from the solution They smell After blooming and decomposing they remove dissolved oxygen from the system resulting in increased biological oxygen demand. The resulting oxygen removal leads to root suffocation Decomposing algae is also a food source for fungus gnats Fungus gnats damage plant roots Suffocated and damaged roots are ideal targets for Pythium attack.

What steps should be taken to stop algae growing?

Algae need light, water and food to grow. You cannot do much about the water and the nutrients but you can stop the light. Wherever light penetrates the nutrient solution action should be taken to stop it. Make sure you have a light proof nutrient reservoir made from opaque material and a lid. Then light proof all the channels, the entry and exit points of the solution.

Recommended Dose Rates

If your initial source of water is a farm dam or pond Coptrol should be used to eliminate algae. It can even be used to prevent an algae bloom as it remains active in the water until algae bloom and is never wasted.

Coptrol will not harm your plants.
