So I asked a pool guy to clean our DE filters. After he left, I noticed that the pool, which was almost crystal clear before cleaning the filters, started to become cloudy. I thoght maybe some of the DE was left in the return line but after a couple of hours, I see that it became worse. I went to look at the filter and noticed that the DE filter valve was in the OPEN position (there are only the LOCKED and OPEN positions on my valve). I immediately turned the pump off then switched the valve to LOCKED.
A few questions, does the OPEN position allow DE to go bacl to the pool? Also, do I have to do anything about the DE in the pool - or would that go back to the filter. I am thinking since there might not be any DE left in the filter, the DE will just continue to return to the pool.
Thanks in advance.
