One of the solutions is a carbon source, so it'd be like dosing vinegar or vodka in combination with the pellets. It should be safe enough if the dose is small. I'm fairly skeptical about some of the claims. Their "coral food" allegedly has no "nitrates and phosphates", which is at best a bit deceptive. Any coral food that contains natural protein is going to have a lot of fixed nitrogen and phosphorus in it.
