Reduce bubbles in Seahorse tank?

[Dale]

How big is the tank? Can you do a sump?

The coralife skimmer also came with a microbubble diffuser. Perhaps you can find something like that for the skimmer.
In my case I reduced the turnover rate quite a bit (they are poor swimmers and don't do well in high flow tanks).
You can also modify your AC unit to reduce it's flow. One way is to snip some length off the blades of the impeller (a rather permanent act). Do this a bit at a time till the desired flow is attained. or, I've heard, you can interchange impellers with a smaller sized AC unit (Just here say. I haven't checked to see if the impellers are interchangeable).
