It's interesting to watch the bubbles stream off the plants… I set the level of CO2 to be just under what will make the plants 'pearl' or bubble with O2...Even with the greater biomass from the increase in growth further limiting the CO2 concentration the plants are pearling. I'm just amazed. Sean Fisheries Biologist
[T]he grow rate has increased but more importantly the morphology and especially the color of the plants has changed for the better. The most noticeable difference appears in a plant called "sunset" Hygrophilia polysperma. The tops of that plant have become bright reddish/pink… Kevin Ph.D. Candidate Integrative Biology Guelph, ON, Canada
The zooanthid corals really change shape under different forms of light. Short stocky bodies under high light (fast growth) and longer stalks and slower growth the less light that reaches them on the compact fluor. With LED [lighting], growth is fast, far faster than [fluorescent] lighting only, and the Zooanthids remain very compact. In fact, buying longer stalked zoos quickly change to a short stalk and use the extra mass to spread quickly (grow more heads). Damian Mississauga Fish Club
