When you say concrete pool, do you mean plaster/gunite? Does it have a liner? If it is a plaster/gunite style pool you need to keep in mind that if the local water table is too high, then you might float your pool if you drain it down too far.AdrenalinPlease said:So I how much water should I drain given that my CYA is between 100 and 140?
