Heya! Pool was solid at about 85 TA for a while, now it's at 60 two days later after adding a gallon of chlorine and 1/8 gallon MA.
30k gal, plaster, 50deg water, copper pipes.
TF test kit
Chlorine (10%) 7ppm
It says in the pool calculator to add 225oz of baking soda to ramp it up to 100, from 60. That seems like a lot of baking soda. Really? That much? :/
Love this site! Thanks everyone!
