im currently using miracle mud...and WOW my tank is a miracle..everything grows twice as fast...hahah NOT
only reason im using miracle mud instead of a deep sand bed, is because of space issues. My refugium is built into my sump, and i dont have a whole lotta room. tried to kill 2 birds with one stone...now i got the mud instead of the DSB....i dont know if it honestly makes a huge difference, but id say if u have the room just go with a DSB....good luck
