Five Steps To Controlling Green Water In Ponds

With Earth Day coming up it seemed only fitting to talk more about a green topic.

And while green water algae isn’t necessarily the favorite subject for pond owners, it is one of the more common problems that we all may face so in this week’s pond tip video I wanted to talk about several of the best ways to deal with the problem, rather than using chemicals. This isn’t to say that chemicals can’t be used but as I often suggest, there may be better solutions for this particular problem.

If you’ve got some proven advice on how you’ve kept green water in check in your pond, please share that below!

  1. Water hyacynth is excellent for controlling this. However it is illegal here in Texas and hard to get. I have found it in some ditches but not this year. I cannot get it to stay alive over the winter and I am careful with it. I keep taking it out when it gets too much and burn it so I am responsible with it, but can not just buy it.

  2. Ireed… One thing we do in our water feature (4 ponds connected by a 130′ stream) is a combination of artificial and natural treatment / prevention.

    Water lilies help and should be ok in Texas, as do planting shade trees on the south side of the pond. We allow our chorus (tree) frogs to breed in the pond in the spring, which produces hundreds of thousands of tiny algae eating tadpoles all summer long.

    We also use barley extract. We do not get green water, but do get string algae and algae / grass growing attached to the rocks on the pond bottom. For these we use a combination of pro-biotic bacteria in our waterfall weir, and chemical solution (Algaefix).

    Hope this helps.
