I have a leak and water was dropping up to inch to 3/4" when it was full . Now the water is below all jets and skimmer and getting lower by 1/2 inch a day. Done bucket test many times and it's confirming the leak. Don't have bottom drain , so must be a leak in a liner . Can't find the hole, the water is still too deep at deep end to stand and explore. Did some diving today, don't see anything suspicious. Tried food dye method , can't find anything. is it easier just to drain it and explore? I'm sick of this situation. and water getting greener since I can't filter and circulate it.
