I am getting ready to do the first backwash of my filter since firing the pool guy and I just want to make sure I am ready to go. I have a DE filter (Jandy DEV 60) that requires 6 lbs of DE. When I do a backwash, how much DE do I put back into the skimmer? The full 6lbs or only a percentage of that? Also, how do I add it- do I mix it with water first before pouring into the skimmer? Is there a "good" type of DE to buy or will any pool-DE do? Any information/recommendations you have would be great! Thank you!
