Mark Weiss Coral Vital: Is it snake oil?

[bcdope]

Just wondering if any Canreefers out there utilize Mark Weiss' Coral Vital product, let alone any product that his company produces?
Ive been hearing reports that it may indeed be snake oil, and the claims that the company makes regarding this product are quite suspicious and unscientific? If indeed there are questions that arise from his products, what would you guys consider to be a 'worthy' subsititute....

BTW, Im not into dosing my nano-tank, for fear of overdosing... I did start out dosing kalk and iodine, but discontinued this practice since much of what is lost (in terms of vital elements and such) is quickly replenished through water changes. Plus its cheaper that way....

Peace
