Quick Cure dip / bath instructions?

[Spar]

I see in searches people saying they did 10x strength (from what is recommended on the bottle for in-tank dosage) for dips/baths with Quick Cure, but wondering if that is the actual recommended strength. I don't need it right now, but want to be prepared in the future...

I've only used Formalin-MS, but I know fellow hobbyists who have successfully eradicated Brook using Quick Cure. They just followed the dosing instructions on the label, and bathed the fish in it for around 45 mins. Usually 2 or 3 baths gets the job done. Apparently formaldehyde is potent stuff, even at low concentrations. Make sure to heavily aerate the bath, as formaldehyde quickly depletes the water of O2.

It depends on what you are trying to cure. If used Quick Cure for brook and to kill very stubborn flukes.
