algae problems- desperate

[KurtV]

Hi Renee,
What's the level of Cyanuric Acid (CYA, aka stabiliser) in your water? That will determine the level of chlorine you need to maintain to keep your water clear and clean (see the Best Guess Table sticky thread at the top of the chlorine forum for more information).

Edit: Just noticed that one of your numbers is labelled ccl, is that combined chlorine? What's the source of your test results? Your own test kit or a pool store? If the former, which kit do you have?
