Thank you Almees! As you can see from posts here there's individuals afraid of questioning their beliefs. :/ There's more and more research every day showing how critical the right kinds of DOC is to a healthy reef. The stuff on cryptic sponges removing and recycling labile DOC (organic carbon, carbon dosing) 1000 times faster than bacterioplankton is just one of the amazing discoveries and I believe essential for long term success! I've set up scholar.google.com to send me links of any research related to Rebecca V. Thurber, Forest Rohwer, Kim B. Ritchie, Jasper deGoeij and Andreas Haas. Just be warned you'll be getting lots of reading material!
