I am pretty handy and I have read a few articles about replacing DE Grids. I am wondering if it is as easy as they make it sound? I have a Pentair 24 FNS Plus. Before cracking this thing open, how do I know what size grids to buy? Also, I have no idea how many gallons my pool is but I'm sure there is something wrong with the grids because powder is coming back into the pool. Any advice would be greatly appreciated.
Thank you in advance. -J
