The brown-green gunk sounds like algae. You stated that you have cleaned the filter. Have you taken the cartridge completely out? If not, I would suggest that you do so. Scrub the inside of the filter tank with a 4:1 bleach water mixture, only 1 part bleach. Then soak the cartridge in an acid bath, like Muriatic Acid. This will kill any algae that is in the filter itself.
You may need to vaccuum your pool to waste, get rid of some of the water and refill it. This may help get the chemicals in order.
Another idea would be to run the system continuously for a couple of days. Vaccuum to waste, not to return lines, and clean the filter when it reaches 8 to 10 PSI above start-up. You may not be running the pump long enough to properly filter water. Keep trying to get chemicals in order.
