Okay it's my first pool and I am trying to figure it all out. I have Hayward DE grid filter. Pool company I was using sucks so I decided to take things on my own. I did a backwash on Sunday and then rinse but did not realize I supposed to put DE powder into the skimmer. Luckily this evening I found a bag of it left by the previous owners we just bought the house. It has been filtering a few days now and the PSI today was really low like 7 PSI. First question is am I screwed and caused a possible issue or if first thing my AM get the filter running and add the 4.5 scoops? Tomorrow I am also going to let the air bleed out which I did not do. The low PSI could not adding the DE cause that and or not bleeding out the filter air after the backwash and turning back to filter?
Hoping I did not mess it up but learning the ropes here.
