So if im understanding this correctly im basically not doing a water change for the next 2 weeks. Yikes. Or just not adding water conditioners. We are set up for chlorine removal with the home filtration. No chlaramine in the tap.

"Treatment
If the bottle has a dropper cap, use 20 drops (1 mL) per 40 L (10.5 US 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). 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.
Finish the Full Treatment
Ich, velvet, and many other parasites spend a large portion of their life cycle as a cyst that is immune to medication and hiding in the substrate of your tank. Remember that you need to finish the full treatment even if you can’t see parasites on the fish!
After Treating
Cupramine can be removed using carbon or
CupriSorb. Leave the copper-absorbing media in your tank for at least a week after the copper concentration has reached 0 to ensure all traces of the medication have been completely removed.
In case of eye exposure, promptly & thoroughly wash eyes with water & seek medical attention."
So for 400 gals (roughly) im using 38 mls. Cut in half for fresh is 19 mls. Wait 48 hrs then another 19 mls. water change in between dosings ?
Then wait 14 days
