There are a lot of DIY Led threads online if you look. I made one for my tank and it was simple, pretty cheap, and turned out great. Just make sure you do your research on them.

After doing some research it looks like the A104AC LED fixture by Acan would meet my needs pretty well. I am going to take another look at the store tomorrow, and will probably have them order one for me.

Here's the latest update.

My tank seems to have cycled quickly. Ammonia and nitrite levels have been at zero for several days. Nitrates were high (>60 ppm) but dropped below 15 ppm with the first water change. I decided to add some livestock, and bought a small a yellow watchman goby and bicolor blenny.

I also picked up a AcanLighting A104AC LED fixture. It was more money than I originally wanted to spend, but it's a beautiful light and won't limit the corals I can choose.

Here's a pic of what the setup looks like right now.

My specific gravity is only about 1.022. Over the next couple water changes, I'm going to try to bring it up a bit.

Here's the goby. Both are settling in and are eating, but he seems very shy.

The specific gravity is only about 1.022. I'm looking to bring the salinity up to a good level for invertebrates. Could I safely go to 1.025 with a single water change?

What are your magnesium levels? You can also bring salinity up by dosing mag..

I've found my skimmer performs better with higher salinity as well.

The question should be what is Mag? Well, Mag is typically a combination of Magnesium Chloride and Magnesium Sulfate. Since Magnesium is a Sulfate, it can build up and increase your salinity over time, especially if not keeping up on water changes. I usually adjust my water change parameters prior to adding the new saltwater to the tank, so never had an issue.

Think Sulfate, Sulfer, Salt, and it should become more clear X.

So when dosing mag your salinity will rise how much are we talkin here? And what brand of magnesium additive are you using? I was under the impression adding mag and kalk will raise ph not salinity?
