What did they give you (ingredients). Have you bought a good test kit like the Taylor K-2006 yet? You can also go ahead and test your fill water. That way you will have an idea of the pH and alk of the water you will be adding and can plan accordingly. (You aren't filling from a well are you?)

How smart you are, to be reading and learning ahead of time. Lots of people here with a big mess on their hands and wishing they had done just that!
