Seachem Reef Advantage Calcium VS Kent Turbo Calcium

[kae]

Are they the same type of calcium (anhydrous)? Why is Seachem more concentrated than Kent according to JDieck's calculator? Which one is better to use?

Thanks for any helps.

They're both about the same. One might be anhydrous, or have fewer other random ingredients. I doubt it matters which one is used.

They are both anhydrous calcium chloride. The Seachem as also includes magnesium and strontium chloride.
