DIY Experiment: Dissolving Calcium Carbonate (shells, dead-coral skeletons, coral sand) in Vinegar.
Note: This method also removes scale from pumps (then brush with a toothbrush to remove organic residues)!
Eventually, this grew white bacteria (without a bad smell) -- which are edible to fish and other organisms.

What happens if this solution is dosed into a reef aquarium?
- Will the bacteria be useful food for the reef?
- Will the calcium be taken up by reef-building organisms?
- Will the vinegar act as carbon dosing, and reduce nutrients?
- Could this method supplement or replace a calcium reactor or be dosed into a calcium reactor instead of CO2?
- How much would one dose?
- At what ratio of Vinegar (Acetic Acid) to Calcium Acetate?
