Cartridge vs Sand Filter: Is Switching Worth It?
Three summers of hauling cartridges out of my filter housing, blasting them with a hose, and letting them dry in the backyard — and I'm at my breaking point. The funny thing is it only really feels unbearable when it's above 85°F outside, because that's when the algae pressure picks up and I'm pulling the cartridges every couple of weeks instead of once a month. During the cooler shoulder season the system works fine and I barely think about it.
My neighbor runs a sand filter and swears he just backwashes it every few weeks and forgets about it. Replacement cartridges for my setup run me somewhere around $100–$150 a pop, and they don't last as long as I'd like. I'm seriously considering making the jump to sand — but I want to know what that conversion actually costs, whether I'll regret the water clarity trade-off, and whether the long-term math actually works out in my favor.
Is converting from cartridge to sand a genuinely smart move for a medium-sized in-ground pool, or am I just reacting to a hot-weather frustration? What are the real trade-offs I should be thinking through before I commit?…more
