I have a recently bought a property with a Phelps Signature Swim Spa with three filters. (one single, one double behind weir gates)
I've noticed that the single seems to be getting much dirtier than the double at a rate maybe 10x faster. The single needs to be taken out and cleaned weekly while the pair haven't needed to be cleaned in 3 months.
It also seems that the suction on the double filter is significantly less than on the single (which doesn't make sense to me).
Has anyone else had this issue?
(Sorry if I'm not giving enough details, I'm new here.)
