Will Air from Filter Harm tank?

[adman76]

Hi!
I am using Eheim 2026.
I seem to have this problem where air keep coming out of the filter. It's very very small bubbles of air. Would it be harmful for the tank? How do I get rid of the air?
Thanks!

Does your filter give out a "grumbing" noise? Or you hear the sound of "water gushing"? If yes, please check if your filter is choked or not.

Btw, are you using a surface skimmer? I noticed that when the skimmer is turned on too big, the filter gives out air into the water.

For me, I usually encounter air bubbles when I wash my filter and when the canister is not full. The air usually clears off after a while. Under normal operation, the filter does not give out any loud noise.

Cheers!

If air is coming out of your filter means it's basically air is going into to your filter. Try to find the source of this 'air leak' and rectify it. It will not harm the tank but it may shorten the lifespan of your filter.

Is this "air" actually the CO2 which you connected somewhere along the input or output of the filter?
Such a filter should pump out air unless air has got in somehow.

aiyah! as long as u got air coming out from your filter and it is not co2, than it could be your filter is not full with water(off and on it, do it a few times) or there could be a leak somewhere which u must go and find.
