The pool is in good shape for its age. The pool inspector (builder) says the ceramic tile and coping around the edges will clean up nice with acid wash. We couldn't test the heater, since there was no propane in the tank. The spa worked, but became very frothy bubbly in about 2 minutes, like soap bubbles. That was kind of creepy. The owner has been using chlorine tabs from Walmart. Thanks for your input. By the time we get in the house, it will be time to close the pool.
