Follow this link it is a good refrence point.
I think if your going to grow SPS you might want to go a little stronger than they recomend.

I would go with 2 250w MH and 4 96w PC.

You should consider buying the parts and building the light system yourself. I dont think anyone makes a system with the config I recomended. I have a Current Outer Orbit which has been great. But thier 48" system has 2 150mh and 2 130pc which will give you about 6 watts per. Should be enough, but if you could assemble your own you can get more for less $.

How big of a piece of green star polyps are you looking for?
The smaller one in the front is already spoken for I have the larger one in the back and others that are just starting. If you want a really big one I'm considering taken the one out of my main tank.

If $ is not a consideration then a calcium reactor is the way to go. For a 90 gallon you could just dose and have great success. You built your own stand, look at some diy plans for reactors also, they look fairly easy to assemble. I dont use one but Ive been looking at the Knop reactors.

Hi, and welcome to ORCA.

You have many choices in lighting. There is no one "right way" Some folks prefer Metal Halides and others prefer power compacts. Just as there are some strong light loving LPS and soft corals there are different lighting requirements for lighting in SPS corals. As a general rule, the more brightly colored SPS coral require very strong light. In my experience, the strongest lighting I have chosen to use and prefer is Metal Halides. And do remember that lighting preferences are and can ne very opinion specific. If you way technical data to support lighting check out any recent literature published by Sanjay Joshi. Google Sanjay and see what you find.

Corals may stay alive under minimum lighting requiremnnts. But corals "THRIVE" and "GROW" under optimal conditions.

There is no magic answer to what you need. You need to do your homework and read posts in forums specifc to your questions. Look at tanks you admire and attempt to replicate what you see.

Good luck,
