What it is: Fiberglass in-ground pool, 5,100 gallons, cartridge filters, located in Arizona
Problems: reoccuring mustard algae, phosphate level off the chart, disappearing chlorine
What's been done: shock, clean filters, shock, clean filters, phosfree (R), shock, clean filters
Result: Chlorine level barely registers & will be gone in another couple of hours and the phosphate level is still over 20,000.
As I understand it, to prevent algae you maintain optimum sanitizer level and eliminate "food" for algae. Algae eat phosphates and according to the levels in my pool, I'm running an "All-You-Can-Eat" algae buffet.
Questions: 1. How can I fix this? 2. How can I keep it from happening again?
I'd appreciate any advice or guidance to help me change this water-filled chemical pit back into a nice little play pool.
Thanks.
