You can see from my logs, I have now been using lower amounts of Chlorine (good) but I'm still wondering why my CC is between .5 and 1.5. It changes almost daily. Also, I tried ti lower my TA by using Muriatic acid. I added what was suggested (3 cups) and it lowered a bit, but not much. I did it again, no change, then added a cup or 2 every other day. Still not much change. Now the gallon is gone, but my PH never really dipped below 7.5. Never saw 7.2. Am I just worried over nothing? Seems like when 1 balances another goes askew. But what is the CAUSE of PH never lowering?
