Either massive advertising, or it 'works'.
From the first picture it looks like you changed your lights, the color of the yellow tang in picture one to other pictures LOOKS different, as well as the glass/acryllic background. Maybe just my monitor/eyes?
Lighting can cause a tank's 'bad' algae to flourish. Sps will not die from lack of their new food source. Carl Weiss, Black Powder is stated to do these things too, and been debated, proven to work. Maybe should look into that? Many people bash it, saying the liquid reef additive looks like apple juice, but now people are adding vodka/sugar to their tanks, helping to boost nitrifying bacteria, therefore reducing nitrates, so actually, if it was apple juice, it would be doing the same as sugar. So he was selling good WORKING products!
But thats besides the point and i could be wrong, i just think that the products you are using are perhaps beneficial in that it COULD contian some sugars, amino acids, such things, corals USE, but im sure you could find the same success with other tried, tested products.
Oh, one last thing, coral (SPS) color does NOT define/indicate health!!!!!!!!
Hey man, us guys in Africa speak english and have internet, guess we can comment on stuff too! YEAH
