Hey all, I've been reading the forums and pool school looking for help, and am still not sure. Just bought a house with 16x32 vinyl inground pool. Everything was fine for first two weeks. Then I went one morning to a cloudy pool. Chlorine level was low. Shocked then pool and left pump running 24/7. Next day the cloudiness had started to clear, but pressure was at 20 psi (normally at ~13). Bumped the filter and pressure dropped back down. That same night the pressure was back up to 20 with almost flow from the jet. I took filter apart, cleaned it and replaced de. When I started it back up, it looked like some de went into pool from the jet. But pressure was down to 12. Went out this am, pressure was back up to 20 but pool was almost crystal clear. Any thoughts on my situation would be greatly appreciated.
