I have always had issues with my DE filter maintaining pressure. I tried cleaning last year and still had issues (I am guessing I did not have enough DE). So I cleaned it again this year and started up the pool. Due to a mistake on my part the filter ran for 30-60 minutes without DE. The pressure on my gauge read 22. I loaded 5 lbs of DE using a 1lb scoop and the pressure still said 22.
I took the filter apart again and the following are pictures of what it looked like.
I was just wondering if this is expected? Also, when I went to backwash the filter, no DE came out. Is this normal as well?
The filter is soaking in a filter cleaner as we speak. Any tips on starting it up again?
Note: I have a large algae problem right now and a proper running filter is a must to help me fight it.
