SPS worries.

I am particular worried in SPS because I see so many die or bleach or losecolor. Even in the LFS tanks. Alot of them have browned out even some under halides. One particularplace that I believe to be a reputable store that has well maintanied tanks. Well there SPS tank seems like it has SPS frags with minumal growth and SPS colonies. one in particular colony that should be purple has turned brown and part of it the branches turned completly white. Is that part dead or bleached?

Im reluctant with SPS because i feel it has low sucess rate. What would cause this in ther tank under 2 400w phoenix 14k bulbs?

 

Browned out corals are still alive. They are just ugly to us. If they are raised in an environment with too many nutrients (DOC, Nitrate, Phosphate), it causes the symbiotic zoox population to grow and they brown out. Put those corals into a proper environment and, over time, they will color back up.

One time I had a supplier ask me if I knew of anyone willing to take gambles on browned out coral colonies (i.e. not just frags). When he told me the price, I bought every single one of them. I put them in the store at dirt-cheap prices and a lot of customers bought them just like that. As they started coloring up, I raised the prices and sold more. When they were really colored up, I raised the prices on what was left again. It was a win-win-win for the wholesaler, the store, and my customers.

 

Getting your feet wet (no pun intended) is really what it takes. I do think they are more difficult, but it is a learning curve.

Browned out corals, as Curt suggested, are a good way to start. Cheap and you should be able to notice the subtle changes as coloration and polyp extention improve. Once you notice that fine tune and your on your way.

You have the lighting and a stable tank, I am pretty sure you will be fine.
