Aquaclear spitting micro bubbles and fuge questions

[chandigz]

Your power head should be fine. The only place it could be picking up air if its totaly submerged is from a bubble. A fuge is basically a refuge(safe zone) conected to your system in which to culture macro algae and pods and such. The idea is that the pods can proliferate in saftey and constantly help to replenish your system.
