Bubble Magnus 5


New member
Im looking into getting one but I have a 120G tank. My footprint is very small and might be able to use the 7 instead of the 5. If I cant wasnt sure if anybody has one on a tank that big. How is it performing and whats your bio load?

You'll want a 7 for sure. Love my 5 but no way it would be adequate for a tank that size

I just received mine Thursday and was very impressed with the build quality. I will be running mine on a 17.4 gallon. For that size tank I would go with the 7.
