Seachem Reef Complete

[Samw]

Hi Guest Jeanna. Thanks for the link. Randy only says that he doesn't like to use Seachem Reef Calcium because he doesn't know where the polygluconate goes and how it affects alk and that its not natural. He doesn't really say its a bad thing.

Reef Complete which I am using however, is a blend of ionic calcium which I guess isn't polygluconate (whatever that means). Does anyone know if it is a bad additive? I haven't found anything to that effect on the Web.

Here's a semi-interesting buyer's guide for Calcium additives:
