So I am reading the only way to reduce my CYA levels (150) is to remove water. So today I started pumping out the water from the pool and came inside to read a bit. I was going to remove all the water down to the shallow end then refill but got frightened when I read that removing too much water can destroy the liner do to hydrostatic pressure. I removed the water to about a foot under the skimmer and am now refilling.
If I can't get the CYA out of the water by draining it, how would one do such a thing?
