Hi... this forum is sooooo helpful, but I cannot find the exact answer I'm looking for. I am confused about how much chlorine is needed to rid my pool of ammonia.
I live in Southeast PA, so pools must be closed for the winter. Last summer, had a problem holding chlorine and determined I had sky-high CYA (from years of tri-chlor and di-chlor). Partially drained in August and refilled. Closed the pool in September to approx. 90ppm CYA. Opened 10 days ago to zero CYA and sky-high pH. Everything I've read seems like an ammonia problem, and the test confirmed 6+ppm (highest reading available was 6, so it may be higher...)
- I cannot find a calculator to determine just how much chlorine is needed to get rid of the ammonia. All I read is "A LOT," but that tells me little
- Can I do this gradually, or must it be big-bang/all-or-nothing?
- Can I use cal-hypo or di-chlor to do this, or must it be liquid chlorine?
- 22,500 gallons, white plaster
- Currently pH neutral (7.4)
- CYA = close to nothing!
