I mix IO and RC. As Myka mention IO calcium is around 360-380. RC calcium is about 450. mixed at 50/50 calcium comes out at 410 but Alk is still a little high for my liking at 11 dKH.
Warning: I have heard that mixing salts can cause "stuff" to precipatate out but so far IO and RC mix just fine.
Oceanic salt is cheap, has a lower dKH but is also high in calcium. I may try mixing Oceanic with IO but the closest I can find Oceanic salt is in Bellingham.
*I'm gonna try bringing 100lbs of white powdery stuff across the border and tell the gaurds it is for my fish tank
