2 months ago I did an acid wash on my pool to remove the calcium deposits in my pebble tec. Refilled and balanced the pool water. I have high calcium at 390 mainly because of the city water that is high in calcium. I added 12 40lb bags of pool salt which brought up my salt level to 3600 (Pentair recommends 3400) moved it all around until dissolved to the naked eye. I am now getting the calcium staining or deposits in the deep end on the floor. I test my PH weekly and I am adding a gallon of acid every week to maintain a PH of 7.5 by the end of the week it is at 8.0. TA is 70. CYA is 30 but I am in the process of raising it to 60 or 70 per the recommendations of TFP.
1. How can I keep the calcium in check? I am maintaining the PH and TA the best I can. My nylon brush removes little if any of the calcium.
2. I have seen some of those Aluminum brushes and thought about going that route but have always been advised not to b/c it would damage the finish... How? Concrete finish vs aluminum, I think concrete is more durable against aluminum. Unless I am wrong, please correct me.
3. The special calcium additives for pools worth its weight in gold? The calcium removers and controllers?
