I'm just wondering what should be done to this fresh water if the pool is not going to get used at all, and will be covered immediately? So we had our old liner rupture last month, and caused quite a blow-out in the floor of the pool. I had also been dealing all summer with CYA levels through the roof (160-180). So I knew the water had to go and the liner was really old anyway. After the blow-out I repaired all the sand and footings, installed a Rhino Pad, permanent stick on cove, and a new liner. Then I filled it with city tap water, (we have pretty good tap water here, well balanced and clean, for drinking etc.) Now that it is filled I need to know what is my best option for the winter, since it is not going to be swam in until next season, I did not re connect the pump, filter or solar heaters (since I live in Maine I take those items and put them indoors for the winter, so they cant freeze, and to keep them more protected.) In years past we would always just bring a water sample to the pool store and they would tell us to put (X) amount of tri-chlor, or similar, in a floating extended release device. But I have decided to stay with the TFP methods, and avoid using those chemicals. So do I still have to get the water fully balanced and chlorinated even though I am covering it immediatly, or is there a different procedure since the water is basically untreated at the moment? Also I would prefer not to have to re-install the pump and filter, since it has to be removed for the winter anyway.
