My CH is 2500ppm after 3 years of evaporation in AZ and after using calcium hypochlorite for the majority of my chlorination. The rest of my levels are proper, it's the CH that's throwing off my saturation index massively. It's also causing scaling. I need to get the stuff OUT!
I've done some reading on the internet and have noticed that using trisodium phosphate (TSP) is ill advised due to the amount of phosphates introduced. I do see a product on the internet called Calcium Hardness Reducer. Also something called Super Sequa-Sol (a sequestering agent).
Does anyone know which is more effective at removing calcium? I have no problem dumping a few bottles of phosphate remover in after the CH has been reduced. I do not have the time to drain and refill the pool and am concerned with my plaster cracking if it dries out as the temps here are reaching 100. Spending money on calcium reducer and phosphate remover is more cost effective as it's less timely for me.
Thanks for your input.
