Thread: pump too strong for cartridge filter

    pump too strong for cartridge filter

    hi there, i suspect that the pump is running very strong so the cartridge filter does not filter well. and the fine small particles were push thru the filter back to the pool. that is why the water is very cloudy.

    i have a single speed pump only.. how can i slow it down or limit the in flow.. ??

    i just put in the new cartridge yesterday.. notice that the suction didn't drop at all. after a few hours clean.. most of the dirt is gone, then i clean the filter again.. and the water is still very cloudy..

    it is like a bit green... and brown....

    It is possible for a pump to be too strong for a filter, though usualy it is because the water has found some way to get through without going through the filter. Could you tell us more about your setup, what size pump, what model of filter, etc?

    That is a very small filter for a 1 HP pump. It will work, but a larger filter would clean up the water faster and not need to be cleaned as often.
