Unless your pump is on 24/7, pucks in the skimmer is a terrible idea. If you don't believe me, try putting a metal encased thermometer in the skimmer along with your pucks. After a few nights with the pump off you'll find your thermometer rusting away. Just imagine what could happen inside the copper pipes in your heater. I'm speaking from experience since I did this about 2 years ago after about one and a half seasons using Tri-Chlor tablets and then finding I had over 100 ppm Cyanuric Acid (CYA) in my water from these tablets and that I could no longer maintain satifactory chlorine levels. Yikes! What a nightmare.

So please follow the advice of others and read about the BBB method on this board. It will not only save you money, but headaches and problems too.
