Wife has seen me in and out and out and about the pool, testing, pouring, spreading, next day testing, etc. Doesn't pay much attention as she thinks I am crazy anyway. Usually stares into the pool and says "Looks ok to me" or doesn't say much. I added boric acid on Friday night. Yesterrday my tests were pretty much in line with suggested levels except FC. Today she comes out and stares again..."It looks clearer, more sparkly" and goes back in. At least I know I'm not the only one and maybe it isn't my imagination. I must say...it really is more sparkly. I know it is only one part of the picture, maybe even a small part but thanks!
