As for adding chemicals, everything you need is already in your reef grade salt mix. Just do your weekly water changes you're already on your way to a healthy tank.

Frogspawns are not low light. I have one doing very well about 12" from my fixture. It's all a matter of acclimating. I doubt this had anything to do with light.

Thank you for the article.
