I drained (50-60%) and re-filled my pool twice and my CYA level is a little above 100.

Alk 150
PH 7.4
chlorine 4.0 perfect .. all #'s are great. I even took my water to my pool store and they said not to worry about the CYA since everything else is great. I manually tested my water and everything always comes out great. I was high on PH and low on chlorine but both of those are fixed. I am keeping it aroudn 4ppm despite's ben's chart but I have 0 algae and my water is crystal clear. I just want to know if my CYA is going to hurt me in the long run. This is my first year converting to the three B's .
