First post, so please let me know if I need to change anything (will work on my sig once I have all the correct pool specs written down). I was wondering, approximately what should the normal, clean pressure on a Sta Rite Cristal Flo filter be? I'm reading about 16, and was curious if I needed to clean the sand/filter before calling it good. I backwashed and rinsed, and installed a new pressure gauge as mine was broken, and this is the first pool we have owned. Any info is greatly appreciated, along with all the other good info I have found here! Wanted to get a good baseline before trying to add DE to my filter.
