Hi, I'm in TX and started using the TFPC method on my pool last year with great results. I didn't close my pool, and other than the annoying part of constantly having to empty the leaves out of the skimmers/cleaner (2x a day in Nov), it went fine.
I did have one issue though, and I wonder if anybody else who doesn't close their pool has the same issue. I was finding that my filter pressure would rocket up to the "need-to-backwash" level all the time over winter. I had to backwash maybe once all summer, but it got to be almost every week in the winter. Obviously all the leaves/organic was putting some stress on the filter, so I guess it makes sense. However, the real issue is replacing the DE. I replaced the DE the first few times, but once I saw it was going to be a regular occurrence, I just stopped, since it would've got costly pretty quick. Anybody else have a similar issue? If so, what did you do about replacing the DE? I figure I'll wait til it gets a little warmer and then I need to do a full filter cleanout anyhow.
FYI - my winter routine: filter/cleaner on 2hrs a day, and I haven't checked the chemicals at all (vs checking them every week in summer). Water is clear and looks fine.
