colour up
 

I am just wondering what do you dose to colour up your SPS or any corals.
I know it depends on the system, but like I say just wondering.

Red Dye 65.... Nah, I'm kidding. Google the SPS colour guide. That'll give you a good place to start. Other than that, top knotch water params and good flow is what you need to get good colour mostly.

1. Good water quality
2. strong lighting
3. consistent levels of calcium, alkalinity and magnessium
