Microbubbles?

[spreston]

Now that I have had my vortech's running for 48 hours, I seem to have alot of microbubbles in the tank, not sand. Is this a normal part of the break-in? I don't recall past powerheads spitting constant bubbles, but then again I've never had anything quite like these.

Is it too close to the water line? If so it could create a vortex and suck some air down into the pump.

I have no microbubbles in my tank with 4 vortechs.

I thought the same thing, but I figured 5" below the surface would to far to create a votex. However, I will try lowering them.

I have mine about 6 - 7 inches below the surface and don't have a problem.

I had them at 4 inches before and it would vortex.
