Some good info about SPS colour can be found in the thread linked.

It is very informative, and certainly turns some of the old beliefs on their head! Also sheds some light on why we get pastel shades in some of those super low nutrient tanks.

Also tells you everything you wanted to know about the "Physiological Chimera" :lol:

Also tells you everything you wanted to know about the "Physiological Chimera"

oh dear! always wanted to know how my natural biological processes worked :lol:

i kinda got lost in the summary section where they said...

Pgmax= 570±60 nmol O2 cm–2 h–1 and Ik=403±27 µmol photons m–2 s–1).

and then continued on with...

(3323±508 and 416±58 nmol Ca2+ 2 h–1 g–1 dry skeletal mass) compared to SC (1560±217 and 225±35 nmol Ca2+ 2 h–1 g–1 dry skeletal mass, respectively, under light and dark conditions). Aspartic acid incorporation rates were also significantly higher in FC (10.44±0.69 and 1.36± 0.26%RAV 2 h–1 g–1 dry skeletal mass, where RAV is total radioactivity initially present in the external medium) than in SC (6.51±0.45 and 0.44±0.02%RAV 2 h–1 g–1 dry skeletal mass under dark and light conditions, respectively)

but other than that, it was highly informative

Did you guys pay to read those articles? It wants me to log on.

Yes have to pay for them Feelers, might just have to settle for the excerpts given in the thread.
