Additives

I agree what christyf5 says....except for the fact that not all salts are created egual.....so that being said, if you use Instant Ocean you have to add calcium and magnesium right off the bat.
I think kent has decent levels of that stuff but their alkalinity is low...i think?
cant remember, havent used it in a while.
Also if I'm not mistaken you have to keep your calcium levels up if you want good coraline growth.
Good luck with the setup.
