Well... venturi is the kind of skimmer it is. It will add in air to the mix at a different time than say, a needle wheel. Needle wheels, like on my Euro-Reef, will introduce air first, before the pump, and a special needle-wheel will chop up the bubbles so they're TINY. There's spray injection too, that will spray a high level of water through a small hole outlet to create micro bubbles. A venturi will add in after the pump, and is considered to be a pain since the valve has to be constantly adjusted. So, as far as I know, there's no brand "venturi"... just the type.
Also, there are two kinds of skimmers... either in sump or HOB
. Do you have a way to add baffles? What kind of sump do you have? Glass or tupperware.
