About 2 months ago I ordered some macro algae: cheto, sea grass, gracillaris, caulerpa, ulva, and some mangroves. I put all of these directly into my 90 gal to eat up some of the phos and help with the gha. After planting the caulerpa, it died back causing the gha to go crazy and the cheto. Once the caulerpa was established it took off. The ulva didn't hold up to good and I was worried about it getting cought in my strainer in the fugium, so I took it out.
When I set up the refugium, I set it up with a 6 inch deep sand bed on one side, 3 to 4 inches of sand in the middle (I know this is not a good depth, but it is not very much. If I see problems, I will add more sand), and I'm going to put a little sand under the cheto today, in the last compatment.
When I transfered everything over, I cut the caulerpa way back. If it gets out of hand in the future, I will take all of it out. I put the whole clump of cheto in and plan on cutting it in half soon and having 2 balls of it in the refugium. The gracillaris went over fine, but I don't know how it will do. I will keep my eye on it. I planted the sea grass in the middle compartment. This has been doing great in my 90 gal. In the back on top of the dsb I have a piece of live rock that has mushrooms, zoas, and some halieda that came up by itself. I first bought the piece of live rock with a yellow fiji on it and some zoas. The fiji lasted a few years and then I lost it. Over the years the zoas grew and I had some mushrooms spread onto it. When we moved into this house, I noticed that I had one piece of halieda growing and over the last few months, it has taken off too.
The refugium is powered by one of the return pumps. It goes through a fluval 404 and I control the flow with the flow control on top of the fluval. I have 6 bags of chmi-pure in the 404 and a little bit of bio glass. If I have to run GAC, I will run it in here too. Its running about 180-200 gph.
I'll get some better pics soon.
Here is a shot of everything under the tank.
I put the protein skimmer in today also. No problems at all.
