On a straight-up empirical level? No question ... this is why some of my assertions & speculations get slapped around merrily by folks like Chris Jury when the discussion gets down to the hardcore, nitty-gritty science.

And rightly so ... fruit loops, anyone?

The thing is, I would suggest that we CAN get at stuff alot more useful than the mere correlations with which we're currently hobbled. MiddletonMark suggested THE entirely correct question. When we figure out what the common variable (or set of variables) which reconciles the "classic" data set with the "bacterioplankton" data set with regards to alkalinity is ... we will have figured out something worth knowing.

When I look at the literature, the linkage between decreased zooxanthellae density, and the terms "starvation" and "bleaching" is pretty hard to miss. Hardly surprising that legitimate scientists & researchers would assert the connection. The ZEOvit system's manufacturer assertions regarding the system's downward manipulation of zooxanthellae density ...absent a coherent, non-promotional explanation of how the system functions ... invites a critical association with the terms "starvation" and "bleaching". It is also perhaps worth noting that both Korallenzucht and Fauna Marin make explicit reference to the risks of lowered nutrient levels when using their products. If they're not talking about something which could be legitimately described as "starvation" ... then what are they talking about?

I've seen the "clearer water" effect in my own ZEOsystem. It's actually kind of impressive: ozone crystal clarity without ozone. You've got to love it. It might also be noted that vodka and/or sugar dosing sometimes ellicts the same observation from users. Even so, I remain skeptical that a turbidity shift is THE causal factor.

No worries, my friend ... ... Happy New Year back at you ... ... and everyone else !
