JoeDizzleMPLS;3582670; said:i should also say that you don't have to use a sponge filter, but they are the cheapest option if you don't already have a filter. an hob would work just fine, just make sure that you cover the intake with either a sponge or a piece of pantyhose held on with a rubberband (that's what i use on the intake of my ac20 on my cherry shrimp tank).
I'm glad you mentioned that because i was just thinkin about the filter on the drive home. I'll go with that since the tank came with a HOB filter.
Thanks
