I have recently added the eheim ecco pro filters onto my tanks and im having trouble keeping the water clean. The tubes are constantly getting caked with stuff on the inside and the water is green
. I feel like this all started when i took the carbon filter out at the recommended 14 days, so i recently changed all the pads even though, it has maybe only been two months added the carbon back and the water doesn't seem to be getting better. Any Ideas?
