    Hello needhelp, and welcome to 3 Reef!

    I know this may sound dumb, but, are the powerheads totally submerged? Some have venturi holes in the top that draw in air .....

    When the pumps work they suck air in via those little tubes, the air goes into the pump which chops up the air and little bubbles appear in the water jet. To stop this from happening you need to either remove the tubes and keep the pumps completely submerged of block of the tube with a clamp or air valve.

    No worries Tom, our pleasure :)

    BTW, a few bubbles in the tank wont hurt anything, in fact I think it can look quite good, others hate them :)

    I have the same problem... i know a few bubbles dont hurt but i had bubbles starting to gather up under rocks and making bigger bubbles. And yes my pumps are submerged completely but they still spit out air every 2 minutes or so...

    not sure but i think that water infiltrates the pump (where the motor is) and thats how it stays cool so i think thats where the air comes from... either that or the electrical wire ;) so im wondering if i drill a small hole on the top of the pump so that the air will get out completely. just an idea.. what do you guys think???

    Thanks

    Marc.

    But im prety sure that water already goes in there.... when you forst put the powerhead in the water bubbles come out from where the power cord comes in the housing so im guessing it would be ok... But now you made me doupt myself birdlady so ill try to take one appart just to see..

    Marc,

    If the pump is completely submerged then air simply cannot get in :) Assuming that some air is trapped inside the pump when installed or cleaned then it will disappear over time :)

    BTW, I totally agree with BL

    DO NOT DRILL HOLES IN YOUR PUMPS
