Hello All,
This is my first time posting. I have an in-ground pool that is approx. 15,000 gallons and plastered walls. The pool is roughly 30 years old. The water is clear but emerald green. I recently purchased a TF-100 test kit and used it for the first time today. I live in California and my thermometer says the water is 53 degrees F. The results of my tests are as follows:
10 ppm FC
0 CC
TA=60
CA=60
pH=7.2
125 ppm CH
I attempted to use the PoolMath calculator and I came up with this list of chemicals to buy and add to the water:
17 oz soda ash
140 oz baking soda
300 oz calcium chloride
(all oz are by weight)
The calculator also said to drain 25% of the pool water and replace it to lower the CYA. Is this a necessary thing? I'd rather not if it's possible, just because of our drought. If I have to replace water should I do that and then retest the water? I assume the amounts of chemicals I need to add would change due to dilution. Or, maybe the calculator takes that into consideration? Also, is there any order I need to add the chemicals in? Do the chemicals and their amounts I got from the calculator sound correct? Any suggestions would be greatly appreciated.
Thank you in advance,
Shane
