pikemartin Posted January 4, 2009 Share Posted January 4, 2009 I understand everything about water chemistry but cant seem to grasp the relationship of alk and calc. As far as coral in my 29BC I only have 2 heads of frogspawn. However, I want to add brain maze, and plate shortly. I have a calc test and the testing shows 380 to 390. How do I go about raising Calc? Simply just add it? I assume you guys will ask me about the Alk but I don't have an alk test. Can anyone just simplify the relationship between calc and alk for me? Thanks Link to comment
er1c_the_reefer Posted January 4, 2009 Share Posted January 4, 2009 380-390 is fine if you're doing water changes normally. if you want to bring it up, just add calcium chloride. simply put, the relation between calcium and alkalinity (assuming alk as carbonate only) is this: raising ca only will lower alk and raising alk only will lower ca. addendum: alk will affect pH, depending on which solution you're using.

Trolldoll Posted January 4, 2009 Share Posted January 4, 2009 Here is a link to a good read http://www.reefkeeping.com/issues/2002-04/...ature/index.php This one shows you how to make your own. http://reefkeeping.com/issues/2006-02/rhf/index.php#5 Link to comment
The Propagator Posted January 4, 2009 Share Posted January 4, 2009 buy an alkalinity test kit, as well as a magnesium test kit. Test for Calcium, magnesium, and alkalinity. Then you will have an idea of where everything is at and whats going on with consumption rates in your tank. Other wise its like peeing in the wind. All you'll end up with eventually is a wet face.
