Issue with Fluval 404
i took apart my 404 yesterday to clean it out.. upon putting it back together like i've always done, and hooking it all up, i turn it on and the motor starts clicking... it didnt stop clicking... i've tried multiple things, nothing has helped...
if i hook the hoses back up, even though they are both filled 100%, it clicks and doesn't flow water properly. if i lower the output nozzle/hose to have it dump out to a bucket lower than the line of the tank, but still higher than filter, it flows well, but still clicks..
here is the super strange part... when i disconnect the hoses, if i plug in the filter with the hose opening just sitting there, it primes and pumps quietly...
