I have just acquired a home with a pool / spa, and starting to learn about it and would like to maintain it myself. I live in Chandler (Phoenix), AZ.
IG 20k gallon plaster pool (30' x 16' x 6') with spill-over spa (6'), circa 2005
2HP WhisperFlo pump w/ AOSmith Century Centurion motor, Pentair Clean & Clear Plus Cartridge Filter
3HP for Spa, 3HP for jets?3/4HP motor for misters
PoolVac In-floor cleaning system
Re: SWC, although a Zodiac LM2-40 controller is there, but no electrodes in the water path. I assume they can't be hidden underneath (or elsewhere)?
I got the Taylor K-2006 testkit, and have the following readings:
FC (ppm) CC (ppm) pH Total Alkinity
Calc hardness (ppm) CYA
Sat. index Comments Ideal range <82F Min: 1.0
151108 72 1.4 0?
Acid demand test: 3 drops of R0005 to neutral 7.4.
140 550 110 0.91 Need
1.6 pt of 10% Cl, 1.72 qt of Muriatic acid for pH. 1.6 gal of Muriatic acid for TAlk.
For the last 2 weeks, I have been using Clorox 3" tablets (XtraBlue from Costco) while waiting for the test kit.
Poolmath with my readings has 3 main suggestions:
- add Chlorine, makes sense. I'll start with buying Clorox from Costco), will look for pure Cl later.
- add Muriatic acid, makes sense.
- drain 64% of water to reduce CYA.
The 3rd recommendation is where I am wondering if I can live without it. Firstly, because I don't know how to drain the pool yet, plus the cost of 13k gallons of water must be quite a bit! Thoughts on this from senior folks here.
Soon I'll also need to learn how to look at the filter I have, and how to clean / maintain it.
