The top photo
This photo shows 3 corals in a row. All of them have considerable reduction in symbiotic algae. The first coral is showing much of it base layer(kinda dark) and the blue coloration is much stronger. The second coral show the reduction in symbiotic algae with better pylop extensions. The last coral (not in focus) was a control coral bought locally. The owner and I agreed that it was totally brown with miminal coloration under MH light. The effect of Ultralith is very dramatic. The second coral picture show the amount of symbiotic algae reduction on the base layer. More pastel colours are starting to show as well a growth increase.
