i use miracle mud & works for me. the reason was to cut off electricity consumption from my tank. some tough times. i cut off my skimmer, GFO reactor, carbon reactor, heater & some other reactor i had on it. did leave my UV though. the reason why i went this route, was because i did end up meeting a marine biologist, a guy that was involve in developing the mud & a water treatment engineer, all in the same place, at the same time. it was like running into the three wise men. i drilled their brains for information. unfortunately, i only retained a bit of their knowledge. all 3 agreed that the more organic your system is, the more it will thrive. especially the engineer, he stressed this idea the most. so i followed their advice. so far my tank has been doing amazingly great. i would say my system is 80% organic. only mechanical thing, is my UV & chemical work comes from a small bag of carbon. i do have a sock, but i have never cleaned it for the past 2 years. they did mentioned that you need an area where detritus collects, for the pods to feed off of. hope it helps. happy reefing!
