How do you like it? Good growth with your corals? Where are you getting your ingredients? I've found much of these DIY formula's need access to the states for some of it.

Right now, I'm trying to sell off my corals but they are too big and I want reasonable money for them. If the formula didn't work they wouldn't get that big I would guess.
I buy the baking soda at the grocery store and the calcium and mag chloride I get from a chemical company here in London. The epsom I get at Walmart.
I buy mostly 25 kilo bags as I make my own salt water as well that I mix half and half with I.O.
I think a lot of people buy from Bulk Reef.
