I cleaned my fish tank and filter last night and when I went to hook the filter up, it wouldn't work. The filter starts up (electricity), but it won't suck any water in through the intake hose. No water will flow into the filter. I filled the filter up before trying to hook up and primed it a bit, but water will not flow. Anyone have any words of wisdom on this?
I'd really prefer not to have to get another filter.
