Didn't see your reply until now...
I went the easier route and bought the packets, one packet per 10 gallons and I added 3.
Each packet is 1 gram and contains 113mg Levamisole HCl.
I must be mistaken on the 1 gram / 10G, don't remember where I saw that, but didn't have a way to measure accurately so paid a bit more for the concise method.
I'm treating the main discus tank now with Levamisole to deworm the remaining fish.
NOW, to learn when Metro, Prazi and Levamisole is appropriate and for what symptoms...
