This is my first year closing down my pool for winter. I purchased an Aquador seal for my skimmer. Am I correct that I do not have to drain any water from the pool if I use this? Or would it still be recommended that I still do drain below the return jet? We do get well below freezing up here in the winter usually...
Also, should I simply bring the chlorine to shock level and be done with it, or would an algaecide also be recommended? And are there any other chemical level checks/adjustments I should be doing before winter, besides chlorine?
Lastly, is there any during-Winter maintenance I should be doing after closing down? For instance, should I be periodically still checking chlorine levels during the winter, or can I just forget about it until Spring?
Thanks in advance for the help! Everyone on this board has been fantastic so far with the help provided! We had a great summer!
