In our tropical climate, algae is the biggest problem. I use AquaPool Triple Action tablets, along with Algicide and Clarifier from a Mexican company . I vacuum the algae out frequently, but it really has been impossible to get ahead of it.
I'm researching ultraviolet systems to see if this might be an answer to the problem. I would not stop using chemicals, but it would be nice to have chlorine levels sufficient for bacteria control rather than trying to kill the algae with it.
Any thoughts? Please remember that we don't have access here in Mexico to all the brands and technology there is in the States. Thanks!
