Hi Berlin;

First things first:

1. Make sure you're maintaining 2+ ppm of chlorine in your pool (unless it's a Baquacil pool).
2. Tell us what size & what kind of pool you have, and what all you've put in it.
3. Tell us what sort of pump and filter you have, and how well they are working.
4. Tell us the last set of test results you have.
5. Tell us what sort of test kit YOU have.
