Currently debating between getting the Marineland Penguin Bio-wheel set for 30 gal
. max....or going with the model that filters up to 50 gal
I currently have a 30 gal
. tank. I'd like to go with the 50 gal
. model (more filtration), but am wondering if this would create too much turbulance in my tank causing my fish to be stressed?
I already have a working filter on my tank (with fish), but the filter is crap and I've been reading some good things about the bio-wheel. I'd rather replace my old filter with a better filter, and keep the old one for backup just in case.
Any advice would be appreciated!
