I have a couple questions about whether or not to maintain the water in a dunk tank and if so, how to go about it. I was thinking I could add water from the pool into the dunk tank. It's a 21000 gallon gunite pool and the numbers are PH - 7.5, TA - 90, CH - 300, Borates - 50, CYA - 50. Is it worth taking 500 gallons out of this and the subsequent drop in CH and Borates or am I better off just adding town water?
Also, if you think I should be adding chlorine to the dunk tank, any tips on how much and how often for either way?
