I think I’m getting thrown off by you saying 8%.
In your 2nd calculation, 11 ounces of salt comes out to roughly 0.08%, which is where you want to be according to the one study on murray cod.
To achieve 8%, you’d need way more salt
Yeah the first calculations were based on number of teaspoons per gallon. Same ratio I used to treat ick. But in the 225 I went up to 7+lbs and it never returned. I just roughly halved it for the 125, using over 3lbs. Just piled it directly on the substrate and the fish ate it too. I probably wasn't clear on what I was reading in the article.
An update: Furan-2 didn't arrive yesterday, very annoying. I'll have to track it. Fish are acting much more normal, swimming around. Outlaw Baby still MIA from what I can tell. One java plant has a dark circle on a leaf. Will monitor to see if the salt is bothering it. The other java is unaffected.
Will do a partial w/c before adding the next round of meds.
