I have a Public swimming pool that has a TA of 180. This high alkalinity isn't causing any problems with the PH or the pool in general. However the state inspector will be coming by sometime this summer and he will want the alk at 120. I don't want to add muriatic acid because the pool is fiberglass and also because i don't want to lower the PH too much and have to shut down the pool. Any ideas on how to slowly lower the alk?
I am adding 2 tri-chlor tabs a day to sanitize the pool. This also keeps the CYA at around 100ppm, because daily backwashing. I also add 1/2 cup soda ash daily. Thanks for any help
