micro bubbles in tank water

[salmonfly]

Hi all,
How do you eliminate those unsightly micro air bubbles that float throughout the tank water (not the ones on top)? They seem to be created by the Marineland filter system as the water flows out over the drain pan. The bubbler adds its' own as well.
Thx,
Scott

Which Marineland filter system??

i had the same problem with my penguin 350 bio-wheel. I upgraded to a canister, and now two on my 46 bowfront. (an eheim 2215 and a fluval 305). I have heard of a few different options. You can attach a block of foam to the output part to stop the intense flow which causes the surface agitation, and subsequently the micro bubbles. Also, taking out the biowheels might fix it. IF possible, id reccomend upgrading to a canister. What filter, and what size tank?
