Very confusing.
If I measure the inside walls of a 20 gal tank and whatever height the water level is at and come up with 18 gallons of water , exactly how much Coppersafe do I need to add each time for 3 consecutive days.
Sorry for such a basic mathematical question but I want to do this correctly, I've seen copper kill fish.
I have a Hanna copper checker and can measure accurately either with vials or syringes.
Thanks for any help.
