cleaning the filter

[jtblaw1]

My pressure has been around 28-30lbs for the last week or so. I backwashed today to get it back down around 20 psi. Soonafter i did it was back up to 28. is opening the filter and washing the fins inside the filter normal maintenance? How often? How do you clean it? if i open the filter will i have to shut off a valve? The top of my filter is above the pool water level. Thx.

Is this your first time using this filter? Did you add the correct amount of Diatomic earth?
When I first5 had mine the instructions said to add 5lbs but the label I found on the filter sad 4lbs, mine no longer needs regenerating every hour.
