Lately it seems like i have to keep turning up my return pump to compensate for it slowing down. Once i clean it, i can always lower back down to my initial settings. I feel like i’m having to clean it a lot lately. So i ask, how often does everyone else have to clean theirs? I’m most interested because I find it to be a pain in the butt.
I know you have't named names or said what "a lot" means to you, but....
Your description sounds like it could be a DC pump. Some (manybe most?) of these are reputed to be designed to operate at especially-low pressure, some AC pumps are probably similar...fouling may have a bigger impact since they don't generate as much force to begin with.
Using a pump with a higher max. head (but same GPH) might be better for your situation.
I noted a few folks speak up about their Mag pumps....my experience has been similar with almost every Model from 3-36. They tend to have more power than some comparable pumps....higher max mead for the same GPH. That means more torque, which mean more resistance to fouling. Dunno if these would be a good alternate for your exact situation, but there are also other pumps out there (even DC) that have higher max head/Q max ratios like this.
You aren't going to get the best power efficiency on any of these pumps compared to lower pressure pumps....but there's a need for that sometimes and that's why both kinds of pumps are for sale. Sometimes it's literally the only thing that will do! :)
