I have a 325 gal Hot Springs spa with an ozonator and Silver Ion Cartridge. The ozonator runs all the time. I have just refilled the spa and here are my test results:
The manufacturer recommends TA of 125-150, CH 150-200, PH 7.4 - 7.6. They also recommend using MPS and Dichlor as sanitizers. They recommend using sodium bisulfate to lower TA and soft water (which I do not have) or stain and scale control to lower CH.
I know by running the jets I can raise PH and lower TA although it will sure use a lot of electricity to run the jets that long. What do ya'll think I should do to get this water balanced?
