I have been reading the forums here for a while but just now posting for the first time.
Basically, we were having trouble with a pool company causing stains every week when they came out to shock. I fired them and am now back to doing it myself. We were having staining issues (10k fiberglass) every time the chlorine level was raised. The endless cycle of adding AA was costing too much and we were on a roller coaster with the other levels.
As of now, the pool looks beautiful but the water feels dry. Maybe due to the calcium? I'm not sure, but I'm afraid to lower the calcium since it seems to be keeping the stains at bay. Thoughts?
