So I'm going to need to keep opening up the filter and hosing them off or just backwashing? Let me see if I have backwashing right. My filter has three in/outs. One has the output from the pump going to it, the other outputs to the pool and the third has a valve on it which I can open to drain it. Is just opening up this third valve and draining it "backwashing"? From what I have read it seems there is more to backwashing than just draining.

The time I opened it up and it was all green, prior to opening it I drained it and the water was all cloudy/green but now if I just let it drain a bit (for like 10 seconds) the water stays pretty clear.

thanks
