This website is amazing! I bought a house about a year ago with an IG gunite pool that is roughly 10k gallons. I've had pool service for the past year but I decided to save some money and do it myself. First thing I did was buy the Taylor test kit (k-2006) and test my water. The results were:
pH = 7.8
FC = 19.5
CC = 0
TA = 250
CH = 1575
CYA = through the roof (only took a couple of drops to make the black dot disappear)
So I decided to cancel the pool service, read pool school, and drain/refill the pool. It's been two weeks since I drained it and my readings now are:
pH = 7.4
FC = 5
CC = 0
TA = 120
CH = 375
CYA = 40
I'm using muriatic acid and generic bleach for chemicals and Kreepy Krauly for an automatic vacuum. Besides the money I'm saving it just feels better knowing I'm taking care of it myself. And I even repaired a leak in my pump and replaced the pool light, saving me at least $300 that my pool company would have charged. I wouldn't have been able to do any of this without Pool School or this forum.
Anyway... to the point. I live in Arizona. Yuma to be specific. And we are recognized as the sunniest city in America. 90% of our year is cloud free. I have no trees to shade my pool during the day, and it will reach 115 degrees outside in July. Last year it got so warm I was tempted to throw ice into the pool to cool it down. Do my pool levels look good for the area I live in? Should I increase CYA to 70 as some on this board have suggested for sunny areas? My TA seems at the high end of what is recommended. Is 120 an acceptable level?
Also, I have some leftover clarifier and metal scaling stuff. Are these good for anything or just a way for the pool company to charge me more?
Thanks for the help!
