Want to provide as many details here as I can, I appreciate any help in advance -
I recently moved into a house with a 20,000 gallon in ground salt water pool with a spa spillover/waterfall with a DE filter. I am having an issue with a very fine layer of dirt (for lack of a better word) on the pool floor. When running a brush along the bottom of the pool, the dirt would kick up and the pool water would become extremely cloudy. The next day, I tried vacuuming it, only to have it return again the next day. A few days ago, I completely cleaned the DE filter and recharged with DE. I checked, and did not notice any issue with the grids, manifold, or pipe itself. The dirt continued to return the next day. I then checked the spider gasket in the multiport valve, it was in awful shape. I ordered a new one and replaced it. At this time, I also added clarifier. Then, I vacuumed up the dirt again. The next day, the issue was improved considerably - no dirt building up while filter was running. However, today, I am still having a very fine layer of dirt on the bottom of the pool but also some in the spa section. I tried brushing it and while I can see the cloud kick up, the pool doesn't become nearly as cloudy as it initially did, even when brushing the whole pool bottom.
Some initial thoughts and notes I have -
-could this be DE returning to the pool? If so, where could it be coming from? I know I added the correct amount after cleaning, and I don't want to add too much.
-the only "red flag" I noticed when cleaning the pool filter was the manifold didn't sit on the standpipe as tightly as I thought it would have. When pressing it manifold down onto the standpipe, it slides back up a little bit. The standpipe O-ring seemed to be intact. Is the Oring supposed to be inside of the pipe on the manifold? Or is it supposed to be on the outside of it on the standpipe?
-pool water chemicals and salt are in balance
-all Orings and gaskets were lubed up with Magic Lube
Thanks again in advance!
