I'm "almost" in the same boat as tldoige; my 30 + yr old gunite pool was re-surfaced last Nov.
The tech filled the pool about 48 hours later and covered it. When I uncovered this spring, I noticed "shadows" (looks like a light grey discoloration). I was told to do a "0 Alk treatment"; but decided to do some homework first. After reading all of the above info; I'm a little confused as to just WHAT I need to do (no, I'm not blonde)! If I'm reading correctly, I should "drain & sand" ???
