I know JasonLion's tutorial stated he has a vinyl liner but I'm concerned about draining the water level 4" below the returns. I read some where on TFP this may not be ideal because it may cause damage to the liner by making it float. I know it doesn't seem to be an issue for most but can anyone entertain this idea for a moment?
Also on average I was just curious how many bottles of antifreeze people use for closing? I saw an online video tutorial where very little (less than 1 half gallon) was used. I have a 16x32 foot pool and the pad is ~12' away from the deep end and I have 4 return lines including the booster line for my polaris.
