draining an inground pool ?
After taking my water sample to my local pool supply company, I was told my total dissolved solids is at 4500 ppm. I was advised that my pool needs to be drained at least half way to lower the solids reading to under 2500. Is it ok to completely empty a Pebble Tech pool overnight and refill the next day without having issues of ruining the (gunite) pool shell? Also what other precautions must I take to ensure not to damage the pool in any way. The pool is about 13000 gallons and is 36' X 20' freeform but only has a max. debt of 6' in deep end and 3' in shallow and also has a beach entry that reduces the total gallons considerably. thanks in advance for your help..
