Why is my aquarium filter filling my water with bubbles?

Question

I have a millenium 3000 hanging filter in my 55 gal salt water tank which i just got and is cycling, on the other side of the tank i have a canister filter. the hanging filter is filling the whole side its hanging on with bubbles and making the water look bad the side with the canister filter is crystal clear? what is my hanging filter doing this and how can i stop it so my tank wont look like sh**** when i put fish in it?

The hanging filter is for up to 60 gallon tanks and 280GPH the canister is for a 30 gallon tank and is 115 GPH

Answer 1

i would just raise the water level

if the water comes in like a waterfall, that's usually the reason you see so many bubbles



Hope that helps
Good luck

Answer 2

Its probably just because the hanging filter pumps water back into the aquarium with a free fall drop. and when the water goes it, it makes bubbles. like when you pour water into a tub. or when you pee. XD
if this is the case, you just need to get the water level higher.

Answer 3

I assume its a feature of the filter, as many filters have air valves to increase oxygenation. Look for a valve letting in the air. Its probably inside somewhere. I'm probably stating the obvious, sorry.

Answer 4

If you use any product while cleaning the aquarium,that may be the problem because when you use any type of product such as body wash product it produces bubble. Or just get the water level higher.
