I am adding a 30-gallon Refugium to my tank to help improve water quality and keep algae in check. I was thinking :thinking: of starting with a 6 inch deep sand bed using 1 - 20lb bag of live sand, and the rest Southdown sand. Is this good? Or instead of 6 inches of sand should I use 4 inches of sand and 2 inches of miracle mud on top of the sand?
I am also confused about the water. I have my Refugium setup above my main display tank and I have used about 5 gallons of the water from a water change off the main tank, then the rest is fresh RO/DI water with new instant ocean salt mix. As of now the Refugium is not connected to the main tank in anyway. My question is will my Refugium start to cycle? I am curious because I don’t want to hook the two tanks together to do my flow testing only to find out I am pumping water that is in an ammonia/nitrate spike into my main display.
Thanks
