Hi,
I have a 150 sqft Cartridge Filter right now with 2 cartridges, one is 6 months old and the other is 3 months.
Now I changed from sand to cartridge 6 months ago (the pool was sand for at least a decade), not sure if that's relevant (is there some micron sized thing that sand lets through that would clog up the cartridge)?
After I spray down the 6 month old cartridge now, the filter looks fine, it basically installs at the same pressure I removed it at, so something has clogged it up that is not being removed by hosing or an overnight soak in normal water.
Should I use TSP or hydrochloric acid or something else and should I soak it?
Thanks.
Richard
