New member, new SWG pool owner. Moved into new house Feb 1st with SWG pool. Pool was cloudy. Pool maintenance guy told me it was due to DE entering the pool. Checked cartridges and found them to be all blown apart. Bought new cartridges and replaced. Pool was sparkly and clean. Happy pool owner. Pool maintenance guy did some research on my filter (Quad DE 80) and informed me it was plumbed backwards with the incorrect hi flow valve (Pentair 26-1152 for Grid Filter only). Purchased and installed new valve (Pentair 26-1055 for Sand Filter). Pool was cloudy again. Checked cartridges again. Found two of them blown out again. Purchased and installed new cartridges again. Pool is still cloudy. How long should it take to clear the DE out of it if everything is working properly? Is there anything else that could be causing this? Please help. I'm about ready to lose it. Any help would be appreciated. Thank you
