Wow! That is beyond impressive....
Call this shilling, call this sucking up for a free bottle from Reef Aquatics.....

We bang out thousands on shiny leds, we spends fortunes on branded coral foods, suppliments and equipment, yet I can honestly say that this is probably the most overlooked aspect of us hobbyists.

Any of you that have dived on a reef at night should have seen the rising mass of zooplankton at night, and observed corals reaction to it...
In fact, in a way, that is exactly what this vid reminded me of... a seething mass of zooplankton rising....
