    cartridge filter not doing a good job

    I just purchased a new 75 sq foot jacuzzi cartridge for my abg 24 foot round pool and it is not filtering properly. I attached a knee high panty hose to the return line and I was amazed at all the particles that my filter was not getting. Should I return the cartridge or is this normal? Please help. My pool is blue but cloudy. Please help!!!

    steady chlorine level about 18
    pH 6.8
    alkalinity 120
    cya 40-50

    Not sure about the filter, but you may want to get your PH up at least to 7 in a vinyl liner pool.

    Sometimes a slightly dirty cartridge filter "cleans" better.

    Most likely the cartridge is not properly seated in the filter and water is able to get past it and avoid being filtered. Either that or the cartridge is ripped or the filter is defective in some other way, both fairly unlikely on a new filter.
