Ok i understand the blowing out of the lines and everything associated with doing that part. Its more so the chemical part i wanna make sure of. So is the tfp method just bringing the fc up to shock level, let it fall a little bit, then the ONLY chemical needed is Polyquat 60? Do not buy a closing kit? None of them floater pill thingys with the blue liquid in them? I used to close my pool by myself with a kit and the aqua pills before it was renovated. Now thats its been renovated anthony and sylvan closed it last year which was the first closing while new. So this will be the 2nd closing on the plaster. Is it ok to the drain below the returns now? Id rather since i have a mesh cover and by opening time its up to level from the winter snow and rain. If i only drain below the skimmer then during winter i have to pump water out about 2-3 times. Dont wanna compromise plaster so if its not okay to drain below returns then no worries.
