Thanks so much for your help. We almost drained the pool, but stopped as it is gunite and as you know, we are swamp filled down here. Just my luck, it would have popped out of the ground before I got it refilled. We started running the pump when the temps started dropping and it is still running. Last year, it seemed like I was having to add more chemicals to the pool just to keep the ph and chlorine numbers right. I pulled a few pool sample numbers the other day and saw they never ran the CYA. As soon as we decide to start, I will let you know and also send some pictures.
