Yes - I don't know - the one link - seems 'odd' in that they are talking about scoops and vials. The one from the Humblefish quote seems to make more sense to me.Are those maybe different forms of the medication? I'm using the powder form which seems to match the instructions from the humblefish link. That says to use 1-2 scoops per 10 gallons. My container says to use 1 scoop per 10 gallons. I used 2 total scoops. So even if I am lower than the 20 gallons that I am calculating on, that is almost half the dosage of the website. So I hope that I am nowhere close to toxic levels.
I don't know - both are instructions for dosing but I feel like this is probably a combo of the stress of the two meds together combined with the trauma from bad shipping.
Thats what I would do. Hope this helps. I think what you said is probably true - that it's a combination of various things. @Jay Hemdal?I didn't think you were saying I did anything wrong. And I really appreciate your efforts and time I understand the sensitive nature of this hobby. I was just unnecessarily vocalizing some discouragement on my part.
I will look more into that protocol once I get past this issue.
My instinct says to do a water change and pre-dose the new water as normal with copper to keep from dropping below my prophylactic level.
