The whole BBB system works very well for me, but it seems like I constanly fight low TA and high PH. The lowest I've dared let TA sink is 50, 8 lbs of baking soda puts me back to 100 for a few weeks. The PH always wants to be high, I add acid about 2 times a week to control it. Is this normal for a 1 1/2 year old 16k gunite pool?
My water is always clear, I've only shocked it once this spring when I opened it. It all seems very easy, just that these 2 readings can't seem to get along. It's been that way since new, so maybe thats just the way it's going to be. The real question is: how low can I let TA go? I never have any problems correcting PH so why does it matter?
