Thanks again Chris For most reefs, I'd shoot for a mean temp of 80 - 82 F Pretty much what I posted as a limit, not need to attempt higher temps. Do you agree with this post or not by Walt Smith and Bomber is the issue on SST. Walt has lived there for almost 20 years or so. And some SST can...

Nice to see you too. I'll do my best to stay out of the...well, whatever it is. As I said, I only skimmed the thread anyway ;) pH = Alk x CO2 makes no sense to me as a conceptual model Of course it makes no sense that is why I called it Dick & Jane, as most don't want me to elaborate on it. In...

No worries ;D

Just a quick comment on temperature: SST is usually a very good descriptor of temp. in the water column down to at least 30 m in the tropics, and usually doesn't drop by more than a 1 - 2 F down to about 50 m or so. SST info from satellites are integrated over largish areas (Pathfinder over a 4...

No worries. A bit on the topic as per Carlo's request: There are 4 species of inorganic carbon that occur in water. They are CO2 (aq), H2CO3 (aq), HCO3- (aq), and CO3-- (aq). The concentration of all of these species is written as SIGMA CO2, or TCO2 and descrbed as "total CO2." At sea water pH...

Whoops! First, coral calcification isn't saturated at 360 ppm. Some corals have been found to be saturated at or slightly above NSW levels while other studies have found that some other species aren't saturated until well above NSW levels (e.g., Marshall and Clode, 2002) but none of them...

Let me preface by saying that I've only skimmed this thread. There are a couple points worth comment though. First, coral calcification isn't saturated at 360 ppm. Some corals have been found to be saturated at or slightly above NSW levels while other studies have found that some other species...
