Green Pond Water

Noelette Hassett asked 10 years ago
I have a large half water barrel that contain a waterlily, marginals and fish. The water is very green with algae. Is this harmful to the fish? What can I do to maintain the water clarity?

If fish are fed in a pond or barrel, they pass out nutrients which encourage algae.These do not bother the fish.

If you want clear water, you will have to install a biofilter and a UV filter, or no fish.
