So I want to redue my refugium. All of my cheato has recently died. I think it was from using the algae fix to clear the hair algae from my display. I now have a red slim problem because of built up nutrients. I look in my refugium and see all of the build up under the skimmer and in the middle chamber all over the rocks. I want to pull everything out and take out what sand I do have in there and go with just live rock. I don't have much rock in there now but want to pack it full. What do you think about me draining the refugium so that I can clean out the waste and restock with a lot of live rock?
