While filling my pool for opening, my well pump started sucking up dirt overnight. Now my pool is a lovely shade of brown.
I have my DE filter going, and we've been bumping about once an hour (the pressure rises 10psi in that time). My manual tells me I need to backwash "when the gauge pressure rises more than 10 psi (.70 Bar) in less than a 24 hour period". Obviously when filtering a really dirty pool, I would imagine this doesn't apply (otherwise I would've backwashed about 10 time now!)
How do I know when I truly need to backwash this thing?
