Anyway as far as brown goes... There are basically two reasons. Either the coral is not getting enough light or it is unhappy with water parameters. As I mentioned before under LED's it is almost a given that bushy corals will at least brown out underneath. I have some of that going on but the coral has good color elsewhere. If you put nothing else in the tank as far as coral additives add coral amino acids. I'm using Aquaforest Coral A and it has really helped my recovering SPS after KH problems to recover and color back up.[/QUOTE]
Again, they aren't turning brown over a course of time. They are changing brown under a different light. And this coral was bought in person, not in photos so there was no enhancing done. I've bought many corals from this store, the only ones that don't look in my tank, like I saw when I bought them, are pink and purple non-fluorescing corals. If I put them under my HOF light I get those pinks in the tank, but I have my HOF over a different tank at the moment and I really don't want to have to have an HOF AND Kessils over my tank, cause the kessils are already WAY more light than I need because my tank is shallow. I was just hoping there was a way, with the kessils to get those non-fluorescing pinks to show, but I guess there isn't.
I can say one thing though, between the extreme color limitation and crappy customer service I will NEVER recommend or buy kessil again. Yes, I think my corals are doing well under the light. They are growing like wildfire (some of them---others I'm having issues with because I can't figure out how to get them in the right place for the right amount of light due to space and have no way to measure how much light they are getting and no room to make shaded areas). I've had more growth in the two months under the kessil than I have had any other light. But I'd like to be able to see the corals that are growing rather than have the pink and purples go bland and disappear. (Like my rock of amazing pink and purple hairy mushrooms) They've practically vanished into the rock work.
