SO LOUD!!!!

  • We are currently upgrading MFK. thanks! -neo
They are supposed to be quiet... try unplugging it filling it with water and turning back on. (you probably already did that)
if that does not work return it!
 
are you able to turn it on full flow rate without it making a LOUD clicking noise? i cant seem to put mine on the high flow rate without it clicking real loud :(
 
check the u-tube for a crack. bought two and both of them were sucking in air from a crack in the u-tube where the plastic was molded together. a bead of silicone later and they are quiet as can be
 
I've been running mine without a cover for years. The cover was vibrating and making a lot of noise.
 
If the cover vibrates I end up putting something heavy on top. Usually a bottle of fish food is good enough if not then the large bottle of de-chlorinator.
