I have an above ground 21' pool, new liner installed this year. Got it filled and has been running for about 1 month. Been in it, but water is chilly 76F. I just recently noticed that the water has an oily feel to it that wasn't there earlier. No sheen or anything I can see, just feels funny. Water looks crystal clear. Any one experienced this or have any ideas on what may be causing this?
Borates: none added, but planning on it.
