2-part Soda Ash and Calcium in BULK NOW AVAILABLE

[Reef Supplies]

Correct, it is indeed hard to source. We want something that won't mess up your ionic balance so we need both MgCl2.6h2O and MgSO4. That is 2 times the headache of the soda ash.

With that being said, we are working on it. We are working on 2 and 3 part combo kits, the 3 part will include ESV mag.

thanks,
