Mkamp:
Your problem is you have been convinced to use all these chemicals you don't need that are expensive and cause problems. You shouldn't have been using either.

99.9% of all pool problems can be cured with Bleach, Borax, Baking Soda, Muriatic Acid and Cyanuric Acid. Toss in ascorbic acid for some stains and you're done.

All these other chemicals are ONLY after you have used our methods of pool care and you STILL have problems.
