Good day everyone. I cleaned my filter today (Pentair FNS 48 sqft) and recharged my filter with approx 7.5 lbs DE according to the chart on the DE box and not the 4.8 lbs directed by the label on my filter itself. Whoops.
I added 11 scoops of DE using a blue DE scoop. I calibrated it before as 1 uncompacted scoop equals about 0.7 lbs. My filter pressure is 11 psi which is typical for my filter after a cleaning and the return pressure is good. Should I be concerned I overcharged it? Can I simply backwash for a few seconds to remove extra DE if you think I added too much?
Thanks,
Daniel
