Diy calcium chloride (A Little Help)

[Myka]

Personally, I only add stuff to my tank that has an aquarium label on it. Aquarium use Calcium chloride is not expensive. Aquaforest sells 5 kg for less than $50 (it is anhydrous and can be used in Randy's recipes). That's certainly more than what that bag of mud cost you, but at least you know what you're adding to your tank. I don't know about you, but I have THOUSANDS of dollars in my reef, and I'm not willing to risk it on a bag of calcium. JMHO.
