did your problem start when you turned on your A/C? that is about the time mine started having the same problem. i apparantly have a well sealed house. i ran a tube to the venture part of my skimmer down into the crawlspace below the tank. this has helped a little.
i am sure Tom will help out on this. i would also suggest searching for anything with ph and tdwyatt in it.
