    Total frustration with my filter

    So every year I battle with my start up of my pool and this year shall be no different I'm sure. I have a freeform 14x33 pool. Tough to calculate gallons on the pool calculator as free form is not an option. Based on rectangular it is 18k gallons but I know it is not.
    I have a pentair 4 speed intelliflo pump with a 420 cart filter. Pump,works great, cart filter is the bain of my existence.
    I know many love theirs and believe me I have tried. I have spent countless hours trying to get this thing to work great and I have failed.....miserably. What does it come down to.......sheer laziness....hating to need to constantly take apart a cart filter housing to clean 4 huge carts every season. I have algae issues every spring, I BBB the daylights out of the pool but fight a filter battle every year. The last 2 seasons I have resorted to purchasing new carts for every season and it helps but is expensive and seems ridiculous.
    I have tried cleaning the carts, I have tried rotating the carts, I have tried washing them daily but I still have not won the battle.
    I am considering a new filtration method....maybe sand? What would be best for my lazy bones that is tired of fighting a no winning battle? Any thoughts are much appreciated!

    Re: Total frustration with my filter

    Whoozer - did you see that? It's a pig flying! Okay, after two full seasons of working with just about every kinda filter....this former Cartridge Fanatic is singing a new tune. I never had to clear my personal pool from "swamp". Ever. Even when it was I considered the bain of my existence. LOL So back in the day on TFP I swore by Cartridge as being "the best".

    Fast forward to now, when I'm recommending my clients replace their occasionally aged/inherited and lacking, and/or malfunctioning equipment, I push them towards sand, or if money is no object - DE. As much of a pain as DE can be, Its awesome. Sand and DE filters, most good set ups will have a recirculate setting on the multiport and a vac to waste setting which carts usually don't. Not to mention having to dismantle to clean. So that's the advantage of the sand and DE, the backwashing... I cleared a green, ammonia ridden pool with a DE filter in less than 7 days without having to clean the grids once. Backwash, yes, but not breakdown and clean. Of course the filter was a great one and oversized so that helped...

    yes bigger is always better on the filter. Dave should chime in - I remember he posted a pic of his filter once the thing is huge. lol

    Re: Total frustration with my filter

    What are the advantages of the top mount as it is currently plumbed for a side mount for the filter cartridge. Just curious. I can replumb but would prefer it to be easiest.

    Re: Total frustration with my filter

    Any thoughts on what size I need? Can't afford DE looking for a sand.

    Re: Total frustration with my filter

    A general size recommendation for you would be a 24" sand filter ... but like has been said there is nothing wrong with going a little bigger.

    In reality, your cartridge should have been plenty big, we would have recommended at least 260 sqft. I think your bigger problem is improperly closing the pool such that you end up with a swamp to clear. If the FC was maintained correctly, I would not be surprised if you only had to clean that 420 sqft filter once a year. But, once you have an algae bloom, the cartridges are certainly a lot of work.
