Wait a second here......Greg, you dove many reefs. Have you seen such brilliant corals there as you do in successful reef tanks? It's our powerful, artificial lighting that makes these corals color up this way. Do they need it? Nope. Perfect example: I gave a frag of a purple valida to a friend years ago and he glued it to a rock and forgot about it in his 125 gallon with 99% soft corals and 150 watt halides over it. It turned poop brown and grew a little, but lived there for about 4 years until he broke his tank down and I took it back off of him.
I put it in the tank at the gym I maintain, and now it has become this-
Are we driving them past their limits? No way. Are we giving them much more than most of them are used to? Yup. Is it hurting them? Nope
