On which, organic carbon dosing/bacteria or sponges?
Bacteria and sponges. Thanks.
Rereading your work on carbon dosing last night and today [emoji1]

It is well known that many sponges feed on bacteria and small organic particles, but I don't have a specific book to recommend. There's a ton of online info:
http://www.asnailsodyssey.com/LEARNABOUT/SPONGE/sponFeed.php
from it:
"Scientists in Barkley Sound, British Columbia have employed an underwater remotely operated vehicle to sample inhalent and exhalent water simultaneously from two species of deep-inhabiting (120-160m) hexactinellid sponges Aphrocallistes vastus andRhabdocalyptus dawsoni to determine aspects of feeding and metabolism. Both species are primarily bacteriovores, removing on average 80% of bacteria from their inhalent streams.Values on the graph below the dotted line indicate feeding. Both species respond linearly to elevated bacterial concentrations over the full range encountered in situ. "

" In general, sponges feed by filtering bacteria from the water that passes through them. Some sponges trap roughly 90 percent of all bacteria in the water they filter."
http://www.mesa.edu.au/porifera/
"Most sponges are filter feeders, eating bacteria and other food particles in the water. The volume of water passing through a sponge can be huge, up to 20,000 times the sponge's volume in a 24 hour period."

Thanks Randy. I have lost some nice hitchhiker sponges in the past. Im familiar with their feeding but not fully husbandry in home aquaria. It seems bacteria is fairly overlooked or misunderstood aspect.
I have to promise myself to read your Carbon dosing first, then look at new pets.
