Third year with this pool, previous homeowner had it for a while. So not sure how old the components are.
Opened two weeks ago - was a bit green so went through the shock/vac/clean filter routine many times. I've been down this road before so comfortable with the process. Got it clear in about 5 days.
But in every prior year, once my water is clear, I can typically leave the same filter cartridge in for the rest of the summer and just treat with bleach here and there. Lately, within a few hours of starting the filter, my filter pressure is up 10 points and there's almost no water pressure coming out of the return. I don't seem to have any leaks, my water is clear, and even if I stop the filter and pull out the filter, it doesn't appear overly dirty. I originally suspected my pump was on its way out, but the fact that the pressure goes from 10 to 20 (new, clean cartridge to several hours old) makes me think it's not the pump. If I take the filter out, spray it down (even though it's hard to even tell I'm accomplishing anything), then put it back in, the pressure goes back down to 10 and the water pressure out of the return is great (for a few hours.
Any ideas? Is it common to have a filter get clogged in a few hours when the water appears clear and the filter doesn't look dirty when you take it out? This is the first time I've run into this.
