I have a little gravel vac thing that is about a third of the size of my python vac in every way (length and girth) and I'm wondering If that's big enough to make a reactor out of or if size even matters (I'm thinking this doesn't sound so innocent as I type it, but I assure you it is).
Should I go to PetSmart and buy a bigger one or is this mini just fine?
