Cupramine Half dose or Full dose?

[ReefKing101]

So I was watching a video of a guy who was treating ich he seems to know what he’s doing and recommend only using half the recommended dose of cupramine as the full dose is to close to toxic. Is this true? I’m not sure what dose I should be going with now

Re: Cupramine Dosing

Where on the website did you see this? The correct dose is 1ml per 10.5 gallons and that is what I see on our product page for Cupramine. You can see the instructions pasted below.

Remove all invertebrates. Turn off UV sterilizer; remove chemical filtration. If the bottle has a dropper cap, use 20 drops (1 mL) per 40 L (10.5 gallons*) the first day, wait 48 hours, then repeat. On non-dropper caps, each inner ring is 1 mL. In freshwater use half dose. Final copper concentration is 0.5 mg/L (0.25 mg/L in freshwater). Leave at this concentration for 14 days. Do not redose without testing (MultiTest: Copper™). Do not use in conjunction with any other medication. If tank has ever been treated with an ionic copper (e.g. copper chloride, sulfate or citrate), test copper level after initial dosing. Although most fish tolerate Cupramine™ to 0.8 mg/L, it is not advisable to exceed 0.6 mg/L copper. Remove with carbon or CupriSorb™.

This video he mentions half dosage is more than enough. I’ll do the full dose then is spreading it over 5 days enough ?
