That's what I hope - that I will not have much of a cycle when adding rock.
FishyFreak - thanks for help with the ID. You know, the problem is if I do a google search I can find pictures of the same xenia name but the xenia in the pictures looks very different.
So I decided to go with a quick fix rig for my fans since I seem incapable of drilling holes in acrylic
Over the refugium I have two 120 mm fans that are attached to two pieces of paneling cap trim (plastic). The trim is long enough to span the whole fuge. The back trim does just that, resting on the top of the fuge. The front trim is hanging in order to make the fans angled across the fuge water surface. I also like the hanging since it prevents the fans from being able to fall into the water.
Here are some pictures of the fans over the fuge. The text in these pictures didn't come out very well...
Over the sump I have two more 120mm fans. These fans are just hooked to each other with very tight zip ties. Then I hung them. They have to be up pretty high so that they don't conflict with all of the plumbing and stuff.
I got all of the wires run as neatly as possible and everything turned out pretty well. I still have not set up the fans that will vent the air out of the stand. So I still have to leave the stand doors open to let some air through there. Hopefully this week I'll get the fans set up in the stand.
Maybe some day when I set up a nicer sump/fuge system I'll also fix the fan brackets up.
