Perhaps I'm getting lost in my opinion of coral health through appearance and growth rate. Because corals don't speak I have no other judge. I do feel that the health of the zooxanthallae through reproduction and byproducts determin the health of the coral. So healthy and growing zoox=healthy and growing coral. Do corals need to grow I'm not sure. I would assume though that in the wild they would disappear with so many predators if the did not grow. Whats a healthy growth rate? I'm not totally sure.
Bob's thought was all the corals need as far as spectrum would be in a 5500k bulb. I geuss I would agree with that. As its been done and is being done. Is it the best? IMO no but I geuss I wasn't asked that.
