Personally, I recommend the Eheim pumps or the Mag pumps for submersibles. They seem to have the best reputation. I use an Eheim, which I bought because it is one of the quieter pumps on the market.
For that size tank I would definetly not skimp on your return. Go with the appropriate sized mag pump. Your return is essentially the heart of your system so do it right the first time
I agree. Aqueon makes some ok products but they are definitely not known for their pumps. Mag Drive and Eheim, on the other hand, are known to provide good, quality, reliable submersible pumps.
