I had my pool resurfaced with pebbles in July and am very happy with the results. I decided to actually take care of the pool this time and turned to Trouble Free Pool. I use a SWG which I love and added borates which gave me a soft feel and super clear water.
The problem I'm having is with acid demand and the problems it brings. Both TA and CH tend to climb out of their range. I built the three headed sprinkler I found on your site and have used it and acid to lower the TA. You will notice from the numbers below that I need to do it again.
The Chemical Hardness in the water started at 220 and has climbed to 475. The CSI index is -0.47. Everything I read says I need to remove about a third of the water from my pool and refill. Since that will change the levels of almost everything in the pool I want to be sure that is the only option.
Thanks for your help and great site.
