i am also a newbe, but a couple of things i can think of. Our cover was on but it ripped and i got some debri, not as much as you though. It took a few times to backwash and put in new de before the pump would work without clogging so fast. Also when the shocked our pool it started making a difference right away. We let it settle out for the weekend and were able to us the vacumm to get some of the debri, i will have to go in there and really work it soon. solar cover has been on for a couple of weeks and really makes a difference! The other thing, you should have a by pass on your water softner??? Or get a water delivery to get the job done fast.....good luck, we are definately still learning on ours....bought the house in october and seems as we have been the 1st to open our pool in the area (N.E.) north of Allentown pa. But we will also be the 1st in the pool!! good luck
