Hello! New here and recently switched over to the TFP method after two years of using a frog system in a 30k gal gunite/plaster pool. I drained and refilled 3/4 of the pool a few weeks ago to lower our CYA build up and haven't had to SLAM. The TA of our tap water is 270 so I've been bringing it with acid and aeration over the past couple of weeks. My question is regarding CH, which I was previously unaware I needed to be concerned with at all. Do I really need to worry about bringing it up? The PH has been holding, the pool is crystal clear, and I'm only adding 2.0 or less CL per day to maintain 5.0 FC.
