Hi all!
Just starting up my (wife's) new 3800gal vinyl liner Endless pool.
Initial chemistry seemed pretty easy following the advice here: pH started 7.8 down to 7.5 with a few oz of dry acid that came with the pool. TA is sitting at 150 nicely, CH is 150, and water is clear and feels good.
I can't seem to keep FC in the pool, though. I add 16oz of 5.25% Clorox, which should give me 2ppm, and a few hours later test none there!
I checked for total Chlorine, and still none. No chlorine odor either, not likely CC/organics using it up.
I though maybe my reagents were old in my test kit, but I can get measurements with a dilution of the bleach solution, so I don't think so. It's only a Taylor DPD kit, I have the FAS-DPD kit ordered, but we are stuck until it gets here.
Then I realized I was likely burning off the FC in the UV sanitizer. Is this a reasonable guess?
I probably need 20-30ppm of CYA if she wants to continue to use the UV, right?
Any experienced suggestions?
Thanks,
Scott
