My pond water is filtered yet it turns green, I tried swim pool chlorine, but I worry about feral cats or birds drinking it!

    Animals can smell the chlorine when it is at a high level. But you still might want to try fish or amphibians that eat algae. With the right balance and a filter, you should have a cleaner pool. 😇

    I have seen barley straw balls for sale in garden catalogs. You put them in the pond, leave them, they keep algae (which is what is turning your water green) down. I think you put them in the pond twice a year, sized for the pond you have. Do a search, there are a number of dealers that sell them, or check with a nursery in your area that sells pond supplies.

    What are those algae eating fish called? They may like a feast. Check at your pet store for advice.

    I would take apart the filter and tubing and clean out all the algae. Rinse everything in vinegar that you can. Vinegar has antibacterial and antifungal qualities that will help with the algae to kill the spores. You can put some in the water, but if you have plants it could effect them. You may want to check with a local pet store that has pond supplies, they may be able to help you with something to use. You can also check online at Drs. Foster and Smith. It is a pet supply place out of Wisconsin that has pond and aquarium supplies as well as all other pets. They are pretty reasonable in price.
