The last 2 nights I have back washed and put new DE in my filter to find it raising from 16 to 30 in matter of hours. My pool is currently being shocked and is a slight green. I did have a DE leak this last week that I have fixed. Could it be that the pump is picking up the extra DE in the pool and causing it to raise the pressure/overloading the filter? Should I backwash and not add my recommended amount and see if it still goes up that fast. I have seemed to get most of the old DE out of the pool but not sure about the deep end because of the water clarity. Or could the filter just be grabbing that much stuff out of the water and has to be back washed that often. When back washing it is a dark dark brown when coming out. Thanks again in advance.
