seaclone help

[JasonJ]

got a seaclone with a maxijet1200.
i've been tryin to fine tune this thing.
but there is alot of micro bubbles. i cant really enjoy my corals and fish
coz of the bubbles.
this thing is in a 20gal.
the only way for the bubbles to not be in the tank. is when i tighten the air valve almost shut. if i do that theres hardly any bubbles in the skimmer itself. is that ok? will it still do its job?
