We will need a full set of current water testing results to be able to help. Test strips don't count. Hopefully you have a Taylor K2006 kit (the one we think everyone should have). If not, you should do yourself a favor and get one. You won't be able to find it locally but can get it through this link:> http://pool9.net/tk/

Don't add any more algae treatment. Typically, they hurt more than they help.

What kind of filter do you have?
