| help with fluval 304 when i change the water in my fluval 304 and then fill it backk up i prime it creating the suction then i'm guessing its the detrius( hay looking stuff) comes back into the tank. my question is what am i doing wrong? i clean the filter about every 2 weeks and the same thing happenes everytime. i have no kinks or loops in the tubes. is this normal or do i have a faulty filter? i still have good filter flow through the water. does anyone else have this problem? |
