SicceVoyager HP 10 Stream Pump - freshwater and saltwater application, for submerged use|4000 GPH

I got the SICCE Voyager HP 10 Stream Pump back on 2-28-2022, but now the pump make Humming noise which is scaring the fishs, not to go near there. Took out the propeller and clean it, but still make nosie. contact their support on 2/21/23, let see what happen. Anyone know what the problem is?Thanks

I decided I needed more water movement in my tank, and this thing definitely did the trick.. gotta be careful where I aim it cause it's pretty intense. I have a 200 gallon tank and this thing can pretty much circulate the whole tank on it's own.. I"m also running 3 Koralias, but this one is way nicer (better be for the price)!

Does everything you need to create water movement in my 180 reef aqaurium. Works perfect!!
