The two pumps I have for circulation both came with venturi fittings ( maybe theyre not actually venturis , but they have the same effect ) with a thin air hose that sucks the air in as the water flows out the front of the pump . They both push alot of air but theyre too noisy for my tastes , so here's a little trick I learned yesterday for making them whisper quiet without losing any air intake :
get an old plastic film canister ( or something of a similar size ) and drill two holes in the lid
jam a tube joiner in each hole and attach the air hose from the pump to one
keep the whole thing out of the water obviously
Viola - now your pump is shooting bubbles out like mad and not keeping you awake at night !
