I am not sure where to begin, so I will list my tests from this morning and then describe what is happening.
FC - ~0-0.5
CC or TC - ~0-0.5
pH - ~6.9-7.0
TA - ~180-200
CH - ~250
CYA - ~100-125
These are my tests after adding 10 gallons of 10% liquid chlorine last night. I have been adding liquid chlorine religiously and the pool won't hold any overnight. The strange thing is that the water is actually crystal clear (when not foaming from aeration, see below).
I have been trying to reduce the TA by adding acid and then aerating, and after only one dose of acid and 24 hours of aeration my pH has not really budged. Also during aeration my pool is producing a foam that looks like a bubble bath and when the wind blows it actually flies around the yard.
My plan is to just keep adding liquid chlorine until it starts to hold and hopefully stops the foaming, and to reduce TA using the acid/aerate method. I am worried though because as of yet the pool's pH has not risen from aeration at all after about 48 hours straight. Below is a picture of the aerator I built with the help of the folks here sharing their experience, that I include in case there is something I should do to make it more effective.
Any help or advice would be appreciated and if I need to provide further information let me know. Thanks.
