Can someone help me I have brand new FX5 ( 1month ) annd the output flow stinks I 've cleaned it out and there was little to no dirt in it. It works well after that for 2 weeks then slowa down again...... Can someone help/relate???
It can do that if there is air in the hosing. Stop the filter, raise the hoses above the tank and restart filter. Good luck!
I found mine would do that if there was too much media in it. I removed the water polishing pads and some of the biomax and everything was fine afterwards.
