Idealy Water Chemistry for Indoor Pool

Postby Albert Heller » Thu 18 Feb, 2016 18:54

Hello, I'm new to this forum and have a question regarding indoor pools.

We have a largish tile pool that hold approx. 49K gallons of water. The pool is sanitized using Ozone and a SWG to provide a base level chlorine. My question is what is the ideal water chemistry for this pool. The local pool store recommends the following

FC: 2-4ppm but the primary sanitizer is Ozone
TC: 2-4ppm
CC: N/A - I've read this is the important one for indoor pools
pH: 7.6-7.8
CA: 150-250
TA: 120-180ppm
CYA: 30-100
Cu: 0-0.5
Iron 0-0.3
Borate: 30-70
Salt: 3100 The SWG is a Hayward Tcell

Are these level correct for an indoor pool? My Ozone generator an Eclipse40 from Del Ozone has other recomendation that are slightly different but again I think those have been setup for outdoor pools.

Thanks

If the pool is not exposed to sunlight which for an indoor pool I assume is true, then you don't need a CYA higher than 30 ppm. 20-30 ppm is enough to moderate chlorine's strength. You don't want copper or iron in the pool. You don't want CC in any pool but in an indoor pool you might have some though the ozonator should help keep that to a minimum.
