I'm still struggling with PH and TA. I realize the two Spa waterfalls into pool will raise PH and the new plaster will also do this. My CH has been fairly constant and currently 250. With the rising PH I'm needing to add acid on a regular basis and this is lowering the TA, so also needing to raise TA on a weekly basis. Seems like my situation likes to stay closer 80 TA instead of 110. I do have some scaling but only right around the spa/waterfall feature. Any suggestions how I can reduce the number of corrections I need to make and create a more stable environment?
