canister filter bubbles

[socomplicated07]

:frustrat: Hi, just thought id see if n e one has had past problems or experience with canister filters blowing out bubbles... cuz im having serious issues w my canister filter blowing out a lot of tiny bubbles...... ive got a marineland canister with a 3 stage filtering system, and a 9watt UV sterilizer... i used all the filter media that came w it, which was the bio-balls, the bio-cylinders, bio-foam, and just the polyfiber crap... its in the filter as listed, bottom to top. it also has a surface skimmer that i removed because i think it was part of the problem, but the bubbles still seem to keep coming every 30 seconds or so itll blow out a small amount of tiny bubbles, and every often you can hear it inside the canister, and itll blow bubble out the spray bar... thats another thing also, should i keep the spray bar submerged in the water or keep it right above the water level, or willl that make n e diff at all..... n e help would be great!!! thank you!!!:D

Its probably got air trapped in it.And keep the return submerged.The more the water splashes,the more bubbles it'll make.

Have you checked all the seals? If everything isn't sealed tightly, it can suck in air. Check any o-rings, etc.
