Hey everyone I am opening my pool this weekend and very excited considering this is my first season opening the pool. my question is when I take the cover off the water level is about a foot , a foot and 1/2 lower than where the water intake and skimmer is , to test the CYA do I test it where out is or do I fill the pool to where it's supposed to be then test it? Just want the best results so I know how much chlorine to put in, thanks
