should work well as a slow drip into the tank, no reason for it not to, the difference between this and a
calcium reactor is that a calcium reactor would use CO2 to acidify the seawater temporarily to dissolve the reactor media (aragonite). Only issue I would think is that there may be a tendency to have the particulate Cruhed coral settle out aws undissolved CaCO3 if added before it can diswsolve into the water column (or saturation is reached due to the size of the dosing bolus and/or rate of delivery)
I have no experience with the solution, but
if it is expensive, I would consider getting a reactor rather than spencind the cash for the product.
