Yesterday I put my Hayward DE ec40 filter back together after soaking with dishwasher detergent followed by a muriatic acid soaking (I rinsed the fingers after each). The fingers came out great and there appeared to be no damage. I got the pool running, and everything was great after adding the 4lbs of DE immediately. Ph was low, so I started with balancing the pool. Filter was running great until I turned it off last night (bumped it 3 or 4 times through the day). The pool had cleared significantly.
This morning I turned the filter on again, and it was working away fine. I put a little more Soda Ash in. After about 2 hours, I bumped it again, and when I turned it back on, I noticed dirty water was coming out for about 30 seconds, and then it was clear again. I've bumped it twice since then, and each time dirty water came out for just 30 seconds once I started the filter again.
Any help would be appreciated.
