Swimming Pool Help!? We have an older pool.Cartridge filter.We've be maintaining it since we moved...

We have an older pool.Cartridge filter.We've be maintaining it since we moved in 6 months ago.However,I own a new problem.After an algae kill sour I used a flocculant to help it float to bottom and vaccumed it up.It worked, but now when I vaccum we catch sight of that everything we vaccum is coming back in thru the jet? we had a wind storm that blew stale some little black seed looking things from our trees a few days ago & when I vaccum it up from the bottom, 2 minutes later it adjectives starts shooting thru the jets!! I don't know if my husband switched some valves or something to on/off when he did the flocculant stuff because we vaccumed it out on the ground, not using the filter. I don't know ample about pool flowage to know why what I'm vaccuming up thru the skimmer/pump is coming back surrounded by thru the jets?
on your system, do you not own a "back wash" after sweeping. That gets rid of adjectives the debris you just swept up. Can you appropriate the cartridge filter out and look at it? My hot tub has the tape filter and I take it out and hose it down to clean.


I ma not sure but its sounds blocked... WE dont' have your system so I would suggest gong to the pool supply store and asking help within.

MY first thought is why vacumnn that big stuff up... WE after storms etc. skim off everything we can and use the net to pick up the bigger stuff (like toads, kernel pods, leaves, and dog hair clumps)

Then we run the pump with the shock (after storm) and after use a clarifier if need be.

Hpeo this helps.
Answers:    Looks like u answered ur own ask. Husband=valve. He
possibly bypassed the filter because you vacuumed the algae right onto the ground. Now, you want to use the filter but the "seeds" aren't going to the filter. Not knowing your system you'll need to either investigate the valve yourself or ...ask your husband.
