Alge issues in irrigation water

Rio_GrandeSeptember 5, 2013

We irrigate using ibc containers to feed drip irrigation system. Our tanks keep getting alge in them. I have been treating with chlorine and dumping them after they sit for a couple days but I seem to have a stubborn case in one of them. Is there any other recommended methods to get rid of it short of limiting light? The water comes from a municipal water source.

RG,

Check out Copper Sulfate. It is used to control algae growth:

Copper sulfate may be hard on your plants. Do your research.

Limiting the light is the best way. If the containers are P.E. you can paint them with latex paint. Sand lightly first.

Also, keep crud (leaves, grass, bird crap) out of the water. This 'fertilizes' the algae.
