I am not looking to start this project yet but have begun researching it. I would like to setup
an area of my
sump as a designated
refugium. (middle section seen below)

I'm going to wait until the tank is fully cycled and has some stock in it before setting it up ( source of nutrients). I have a great
LFS that is very helpful and contrary to most
LFS around, is great about not pushing products on me. The owner however is a firm believe in the ecosystem method. He says he has been using it for a few years now with great success. He is using miracle mud as the substrate for his
refugiums. I wanted to hear some opinions on here about where or not there is any "miracle" in this stuff (usefull nutrients,
trace elements etc) or if Im equally better off using a regular
aragonite DSB. Also what kinds of
macro algae should I place in the
fuge?
