I'm new to this. When I took control of my pool a few months ago, I drained the DE filter, disassembled it, and thoroughly hosed it down before reassembling it. Then, because DE irritates my skin, I replaced the DE with cellulose.
This week I had a minor algae outbreak, so I had to use a lot of extra chlorine, and I understand I need to clean the filter. (And the filter pressure is up by about 10-15% over normal.) Should I backwash it or disassemble it? What's the difference? Why would someone do one vs. the other? (I assume backwashing should be a lot faster.)
(Part of me would like to disassemble it so I can see the cellulose on the filter grids so I can see how well they got covered and if I got the quantity right. I still have no concept of whether the cellulose is performing better/worse than the DE...if I put in enough at all.)
