I have a Red Sea G2+ 200 and in the sump the RS Skimmer and Reefmat. I am wanting to put in a refugium. However, I am unsure of where to put it. What little space there is in the cabinet for a hang on is taken by the pull out controller panel to the left. Can I put it in the same chamber as the skimmer?
All you need is a small CPR refugium. Your sump looks really small though. might want to measure to see if it will work for you. The small one will hang right off my skimmer compartment with room to spare on my new system. The size isn't as important really as all you need is a safe place for these organisms to be able to reproduce. They will move out to the tank and populate the rock too. A small refugium is capable of keeping a relatively decent sized tank populated. Not eveything that makes it out ot the tank is eaten. Things will start populate the rocks and everything. You will definitely notice a lot of pods in your tank after a while which is good and after that, your corals are going to start being much happier and you're going to see the fish picking at the rocks a lot more too because they're eating.
I've never looked at a refugium in the context of nutrient export, though it will anyway.
The benefit to me, is how much food for the tank it produces. And that's all live food, not dead food...and just because you can't see it with the naked eye, doesn't mean it's not all there. The best substrate in a refugium isn't sand. It's mud. The mud will support a lot more life/types of life than the sand. There is nothing particularly magical about it. Just the particle size and makeup. They say it will release necessary trace elements, but I can't really prove that so whatever.
Buy a small box of live rock rubble from tampa bay saltwater to start it if you want things to take off quicker.
Also, keep the refugium out of the sump. That just makes the whole thing a PITA to clean and put the refugium output to your pump compartment if you can help it at all to ensure anything that comes out goes up into the tank.
A mud refugium was the greatest addition to my tank. The tank just didn't do anywhere near as good until I did this.
Then everything came together. I can't wait to see how it does this time...
