What are the true benefits or disadvantages with using miracle mud in a refugium. I have an established 150 gallon reef tank and want to install a refugium in the sump using miracle mud and algae will this cause my tank to re-cycle? I watched the YouTube videos about miracle mud but the majority of the videos are presented by ecosystems (the company which sells miracle mud) and I am want to hear true testimonials about the product. Thanks for your feedback
