Question: I live in arizona, have an 18k gallon pool. When I first moved into this house about a month ago the pools water feature (basic rock waterfall) was gross with algae and black fungus all over it. It is all clean and clear now, but wondering how often do I have to run the water feature to keep it clean? Right now I have it running every night for 6 hours when the vac is running. Could I run it every other night instead? Every night but for just two hours? Twice a week? Any recommendations?
Thanks in advance!
