I recently bought a Visi-jet protien skimmer for my 20 gallon sw. I had to cut the reaction tube practically in half to make it fit however. It works great but puts a lot of "fizz" into the tank. The venturi doesn't seem to work at less than 60 GPH even with the air filter removed. Is there any way I can reduce this effect?
