We have a 12K gunite pool. It was built approximately 5 years ago, it has never been drained. At this time it has a salt chlorinator, I believe is not working, it has always be a high demand of acid in this pool, and the chlorine level has also been low with some algae's, and high phosphate reading.
Three weeks ago, I decided to switch to chlorine tablets, after using a phosphate reducer and cleaning the filter, and bingo, there are no algae's, the PH reading are in the proper range. This week I got a reading of Total Free Chlorine that was a little high according to the pool store, also the Calcium reading is showing a reading of 550, the pool store says is also on the high side. The water is clear. I also installed a solar heating system in the pool so that the grandkids can swim all year long. Is there any recommendations for maintaining the proper levels of Calcium Hardness?
