I just refilled my spa and started the testing procedure to balance the water. Fought with a high pH and low TA situation for a while. Is there a trick to get this situation under control? I just about have it after multiple dry acid and baking soda additions.
Then before adding anything I thought I would test the bromine/chlorine reading for fun. I had detectable levels prior to adding anything. I assume chlorine in the city water? THen I added a capful of MPS and now i have 2ppm detectedwith oto, 1 ppm detected with DPD, and 4ppm with the FAS-DPD test...
Is this typical? I still have ha hard time grasping the bromine residual and MPS balance issue.
Thanks!
