A big thanks to all who replied. I'm not excited about the bryopsis, but am glad it does not look like anything other than cyano and GHA in other parts of the tank. I know there are a couple of threads on using Tech M and I may start a thread of my own detailing my experiences with it. Certainly good husbandry is a must for my tank in general and I will be continuing to monitor my levels and keeping a clean tank otherwise.
