Is Vital Reef DNA Bad?

[stresco]

I was told by one LFS that i should be using Reef Vital DNA for the LR in my FOWLR. Then on Friday i was told by another LFS that this stuff is terrible for my tank, and in fact i was polluting my tank everytime that i use it. Is anyone else using this stuff? What is your opinion of it? I would like to hear if i am indeed polluting my tank, or if this stuff is as beneficial as the first LFS says. If you have tried it and changed, what are you using instead, or do i really need supplement for the LR in my tank?

LR does not need any special additives to make it speed up the growth of coralline. I would suggest you just heed the basics. ;)

Coralline will grow rather quickly when the proper levels of alkalinity, calcium and magnesium are maintained and balanced. The amount of light you have is just fine. In fact the lower light levels will promote many different types of coralline that are not easy grown in much more intense lighting set ups.
