hell yeah !

I want to try work out whether I can get away with buying a 35watt air pump and having it quieter than the 2400LPH pond (water) pump but still push as much air as this one does with the venturi on it

it seems to push a heck of alot of air , but its too noisy for my liking - dont like having it on at night
