Hayward 4820 progrid DE with 1.5hp motor.

Ingound pool

Filter is moving from 12psi to 30psi within 30mins of backwash or 90 minutes of recharge.

I have run the filter without the grids with no issue. Cleaned and also replaced the grids with no change. I used the hayward recommanded 7 lbs of DE and the internet suggested 4 lbs with no change. Running the skimmer without the vaccum on and cloudy water as it is cleaning. The grids do get dirty, but a full tear down daily seems like alot. Is it normal to need a fully grid cleaning daily?
