Please help with macro problem.....

[naterealbig]

Hey everyone, thanks in advance for checking out this thread, and any help you can give me. I have a 60gal main tank with a 20gal long being used as a refugium. I have LR, hermits, Chaeto, and grassilaria (sp?). I have micro bubbles going through the fuge, that are sticking to the macro. I didn't see this as being a problem, until I saw that the macro is actually floating now (partially out of the water). I'm worried that one, the micro bubbles will inhibit photosynthesis, and two, that the algae that is actually outside of the water is going to die. I've been able to eliminate the bubbles in the main display by using some floss after the refugium, but haven't been able to eliminate the bubbles from the refugium itself. Will any of this affect the chaeto/grass ?

What kind of flow do you have in the fuge? I have a similar thing going on, and it doesnt seem to affect the macros. The floating actually helps the macros to tumble, and therefore get more light around it. Perhaps someone else will have a different opinion.

Well, I use a Mag 7 as my return pump, so with about 6 feet of head total, I would imagine I'm getting maybe 450gph through the sump. You mentioned the tumbling, but, the algae just floats to the top. It isn't really tumbling at all.

I had the same problem with bubbles in my refugium, and yes it causes the algae to rise and eventually dry and die at the surface. You just need to eliminate the bubbles.
