After testing with the bucket technique I can confirm that I definitley have something besides evaporation going on. I tried taking a little Phenol Red and testing around the skimmer and the return jets as well as the stairs and found nothing. It is possible the leak is around the main drain but I haven't had a chance to test yet. Up until last fall this was a bauqa pool. I fear that the switch to chlorine may have exposed or created a pin leak somewhere in the liner in which case I may never be able to find it. I don't have an endless supply of Phenol Red and time to go around every inch of the pool. Plus even with the dye the leak maybe small enough that I couldn't detect it. The cost of water in my area is very expensive so running the hose for an hour or two a day to replace what I have lost is not an option. The liner itself appears to be in good shape since it has been on Baqua up until last year so I hate to think I would have to replace it plus the cost of refilling the pool would be unbearable. I have not heard back from my pool guy but I'm not real sure what else I can do.
