I just tried backeashing my pump and none of the gunk came out. This was very unexpected.
I have a feeling that my pool guy forgot to load the filter with de after the last backeash( I let him go about two months back for other other pool maintenance related reasons).
The question I have is if the pump has been running for the last two months without de powder what are the adverse consequences? Are the grids toast or will I be able to recover them. I haven't opened up the filter yet.
Let's say the grids are good. Is there a special de grid cleaner that I can use to take care of the organic material that has probably been pressed into the grid by now.
Please note that the reason I was backeashing in the first place was the pressure was too high on the filter. Could this happen even if the pump has been running without any media?
