no thats the complete ideal setup. You wont burn anything but you'll get maximum growth

Everything Looks Good Except Coraline Any More Suggestions On Why It's Not Taken A Foot Hold Yet?
It Was My Thought That With That Much Light I Should Have It Everywhere.
The Only Thing I Have Not Tested Yet Is Magnesium And I Got A Test Kit Ordered Should Be Here Tuesday.

500cal is too high in my opinion. slowly bring that down and alk up a little. your coraline will grow when you have everything in order. i have noticed some rock types do take on coraline at different rates.

There is a chance that you dont actually have any coraline in your tank. It doesnt just appear magically, you have to introduce coraline on rock that you put in the tank. Maybe go to your lfs and try and find a piece that has some on it. Once you get it home, while holding the rock under water in your tank, scrub it lightly with a new toothbrush to release some of the algae spores into the water. When they settle back down they should start growing and coating your other rocks.

lots of coraline types (there are many different types) like lower lighting, so it may take a while for a higher light loving coraline to grab a hold and start to take over in your tank. and as dragon stated if it hasnt been introduced it wont spread, also I have notice through past expirimentation, that it likes higher flow and seeds faster if you take some and scrape it off a rock and put it into a high flow situation (let a powerhead suck up and spray out the particles). It also takes several months for coraline once introduced to hit peak growth rates (usually). I hope this helps good luck.

I was told that there is "never too much lighting" for saltwater it does seem that your calcium is a bit too high, try to bring that down to around 420-435, use alk and purple-up to get a lot of coraline in your tank, but make sure that you keep everything steady if you don't then it goes to waste
