Should I leave the tank light out? Just as I would with Quick cure? I have never used Maracide before in my tank and wanted to know

Thanks for your help,

I personally turn the lights out with any treatment that contains Malachite Green/Formalin when I use them. Light is supposed to deactivate the drug.

Hi Devs
Thanks for letting me know. It sounds like a silly question I know.

Thank you!
