Just curious if the only difference between the size of the pumps is how much air it spits out per second? Or is there something else to take into consideration?
I don't know which pump to buy....

Well you get what you pay for, more expensive pump will probably be queiter and last longer, my aunt likes her tetra whisper pump, I have an older tetra pump and love it so I would have to say tetra is good. Now how big you want it, that depends how many things you want to run with it.
