Fluval 305 on a frag tank

[brisco15]

So i rigged up a fluval with all new hosing and coupler to fit the bulkheads on my frag tank.didnt think about the bubbles do to it sucking in so much air at the output in the tank any suggestions on cutting this air stone effect im getting from my filter out.Don't have to do it this way just thought it be fun to see if it worked.Any and all help will be appreciated!!!!
