Even still, it will give off strong vapours at first, so make sure you use ventilation and do not breathe in the fumes. It dissapates when mixed. Eli's mix 1-3c per 5g) is about what I use. Even that can last a while.
Also cheaper than constantly buying 5L vinegar containers. Ive also used it to dissolve coral skeletons to add back to the aquarium as part of dosing(Makes calcium chloride) but not 100% comfortable with the purity of it (anyone know?)

I have used it the same way as dissolving coral skeleton to a specific PH and back into the tank...Had a riteup on this years ago as it releases unsolvable ions that will ruin your tank parameter leading to coral death,...funny,...as this is brought up...Try vinegar with calcium hydroxide safer method.
