New guy here and thanks for letting me join.... I'm a home pool owner, a bit of diy guy. Not much but I try. We just had a new liner put in. I always took care of my own pool as best I could and I now have dedicated myself to upping my game. Getting the chemicals balanced correctly rather than good enough might give my equipment a longer life? I'm maintaining my own in-ground (15 year old) pool. I believe it is 30,000 gals tops. I have a Hayward sand filter and it needs a little work - spitting out some sand on backwash..and my pressure is reading 30 which is 5-10 lbs more than I recall it's stable pressure reading, usually 20-25. I also know I have air in the line, as my pump water seems to be a whirlpool of energy. Frankly it has always been that way. I just put a 2nd new motor in my Hayward pump so I am getting the idea my system is old obsolete and in need of better care than I have given it. That is what has brought me here. Glad to be here
