My pool is approx 1 year old, details in my sig. The calcium hardness from the tap is 150, but about every 2 weeks my hardness is going up about 15 points. Once it gets up to 450, I have been draining about 30% of my water and refilling and it brings it back down to about 300 and then it starts going up again.. The pool store(Leslie's) says most people have to actively try to raise their hardness and I am the only pool with this issue that they have seen. I have checked my SWG and it doesnt look like it has build up in it.
What could be causing this?
EDIT: I am getting white flakes in my pool when i wakeup they are around the bubblers, my PB says they are "Calcium flakes" but i dont understand where they could keep coming from. I have replaced filter my and the issue persists. I was having to use heavy amounts of noPHOS to get my phosphates down (were up to 3000+). Could the noPHOS be doing it?
