I just put my Cpak skimmer into a different tank and it will only produce big bubbles(rio 800 pump double venturi). I clean the impeller and air tubes, cleaned the venturi, and adapter tubes. its getting plenty of air but only big bubbles and pumping to fast i got the lines hook up right in the manual. It just was working righ an hour ago but now i change tanks its only big bubbles not the mirco bubbles. Never had a problem like this. Trying everything. It's doesn't want to suck the air through properly. thanks. any ideas?
