Is this too powerful for a 20 gallon? I'm thinking about switching my filter over to this, but I'm not really sure if it's meant for larger aquariums.
I know that the more filtration, the better but I don't want too strong of a water flow coming from the back of the tank and making my fish not want to swim near the filter, or stressing them out. It's just hard to tell what a new filter will be like without hearing recommendations and others' experience first.
