This is my second post, so hi everyone. it looks like i can lear a lot here and make some friends in the process. i live in houston, but travel to austin a lot to see my brother. I have a 75g Reef tank with a few corals and fish, and a 30g sump/fuge split longways.

Here is my problem:

I have micro bubbles in my tank. I have tried many many things, including sponges, baffles (many of them), the filter socks, and i still hae bubbles. im beginning to think it is from my crappy Sealife Systems skimmer. If you have any suggestions please chime in now.

Otherwise, should i go ahead and just proceed with my next idea, which is setup the 30 gallon next to my reef tank, and make it kind of a display refugium, have a new sump underneath, and run a nice external skimmer? With this idea in mind, which skimmer should i look at. i would like something i can turn down the flow on because i do plan on upgrading to a 180 in the future, but space under the tank is limited. Any ideas?

PS
one crappy sealife skimmer and 20g wet/dry fuge will be for sale very soon.
