Dirty water back in to pool from cartridge pool filter

I have an approximately 12,000 gallon fiberglass pool. It is about 5 years old and is cleaned by a "predator 175" cartridge filter made by american products. This is the problem...when sweeping the pool and within seconds if the pool is dirty it will start spraying cloudy/water back into the pool. The filters are not dirty and in fact they have been replaced several times with no help. Is this a defective filter and is this normal for cartridge filters? Thanks for any advice or help!
