I would love it if I could get some free advice from some of the pool experts and moderators. I just got my Taylor K-2006 test kit (Yay!!) and now I have solid numbers for my pool. Here they are -
CYA 110 (measured ~55ppm using a 50% diluted pool water solution)
CH 500 (seems a little suspect to me so I may check my fill water and re test...however, I do live in AZ so, ya know....)
Sat Index -0.2 (from wheel decoder in kit)
SO here' my plan of attack :
1. Get my CYA to 50 using lots of drains/backwashes over the next few weeks. Pentair IC-40 manual says 50 as the max level but TFP has different recommended value so not sure which to use....
2. Keep my pH down at 7.4 or lower and try to bump up FC to 7.0 with bleach all while keeping my salt levels in the sweet spot of 3500ppm (Pentair recommends 3400 for the IC40)
3. After I get to a sweet spot established, go "ALL IN" on borates and get them up to 50ppm
Am I missing anything? Can I just get my TA down through acid/aeration process?
I think I'm not going to worry about my CH too much because I already have some Ca scaling on the tiles by the spa...I just feel likes it a losing battle down here in Tucson unless you do lots of water drains/refills. Maybe if I ever get a salt water softener hooked up to the house plumbing, I can control the fill water better but my local water reports always put it at 280ppm so there's no going lower than that.
Thanks and let the free advice roll!!!
PS - I can't believe how HORRIBLY INACCURATE the OTO Cl tests are!! I've been using my dinky little PoolMaster test kit since last year and not only is the Total Chlorine value way off, but there's no way to distinguish FC/CC....other than being a Yes/No test for Cl presence, it's a royal waste of money and time.
