DE Filter, excessive bumping

[aimee3]

We just got a new DE filter this year ( we had a cartridge before) I hear everyone saying that they dont have to bump and backwash often, but it seems that my pressure goes from just under 15, up to 25 every day, sometimes twice a day. Im always bumping that thing. Every few days it jumps up to 25 more than once in day and i backwash it. THe water coming out is always gross.. sometimes white, sometime yellow-y.. even when the pool is clear. Why is this happening when the pool is clear and clean? Am i doing something wrong?

Edit by Poconos: Aimee, I started a new thread with your question. You have a very valid question that deserves it's own spot and you'll get more responses this way.
