i am having problems with my fluval 405. It runs good with nice flow for about a day then it is reduced to a trickle. I clean it and to prime it I run a power head to pump water in the Inlet until there is powerful flow for a few min. Again it will run with good flow for a day or two then slowly reduce to a trickle.
Any ideas what might be wrong. It's a bit of a pain running the power head thru the inlet everyday to keep up the flow...
