Another Newbie Question

[Nano]

different strokes for different folks so it seems, there are tons of opinions and ways of doing things, no way is right or wrong per say, but there is always a better way. I have heard of people not using dosing units either (I'm new by the way lol) and I am currently not using one, and my corals are growing! not in huge amounts but they are growing. but let some one a little more experienced then my self tell you the "right" (best) way for things to flourish.
