Cartridge Filter slows down flow too much

[hythemr]

I have an inground 6k fiberglass pool, with a Jandy 1 1/4 HP pump and Tropicflo cartridge filter. I'm needing to clean my filter weekly to keep the pressure from building. I was dumping some water and left the cartridge out and flow was amazing. I've had the same problem every year, with different brand cartridge replacements, We only have a 4 month pool season here in Michigan and I change them annually. Any ideas? Thanks

How are you maintaining your pool? Pool$tore or TFPC?

All I buy from the pool store is liquid chlorine, I do have it professionally closed every winter.

If you filter is clogging frequently, that usually mean you are fighting an algae bloom (and yes even if your pool looks "fine"). Have you tried an OCLT?

Pool School - Perform the Overnight FC Loss Test (OCLT)

What are your current test numbers?
What does it look like when you clean the filters? Hard crusty stuff or soft slimy stuff?

I would definitely do the OCLT, additionally If you get a fair amount of visible debris a hairnet in the skimmer can cut down on the amount that gets to the filter a bit. The biggest befit is not having to empty the pump basket I only do that every couple of months if even that often.

While a 100 sq ft cart filter works it is really small, I have 100 sq ft cart on my hot tub, it has 700 gallons

A 320 sq ft would work way better for you but if you have algae it will still clog up, how are you testing your water?

I hope this helps

I have to Slam my pool every year I open it, extremely cloudy for about 2 weeks.

The filter is mostly white cloudy water that comes out of it, very minimal slime or hard particles.

I have a Taylor kit, FC & TC are equal.
