Thanks very much Brandon for that info. I'll have to get some of those goodies for my cryptic spongesI’ve actually been using the Zeovit system to grow the bacteria. I used the reactor which I shake every day and I dose the Zeobak, Zeofood and Of course Sponge Power. It funny that I don’t culture it since I work in the Marine Microbiology lab and I have access to all of the media and equipment lol. Anyways I also use Brightwells Phytogreen S which contains phytoplankton in the 1-2micron range and that is dosed every day as well.
