Another difference is that Captiv8 has you maintain natural sea water levels, while Moonshiners has you maintain many of the traces at an elevated level, some of them massively elevated. For example, on my last ICP Captiv8 said my cobalt was over 50 times the base level, while Moonshiners said it was slightly low.I just sent my first ICP in and am awaiting results. I am torn between Moon Shiners and the Captiv8 method. Seems to get you to the same place, but it looks like Captiv8 is easier, cheaper and can be dosed in one liquid as opposed to multiple dosing. Anyone have Captiv8 experience?
There are very successful reefers that use each one. For example, Chris Meckley is on Captiv8, while Andrew Sandler is on Moonshiners.
FWIW, there's a brief discussion on Captiv8 vs Moonshiners on this week's episode of the Reef Builders podcast:
