For treating fungal infection Ive read 6mg per gallon for 5 days, but yeah this being a 1 dose deal i wouldnt be concerned about 10mg per gallon. That is the dosage I think ill do. Ive got 17 gallons of tank water in my 20g. Ill weigh out 170mg from one capsule and hold onto the remaining.
I agree. You would think that there would have to be a substantial amount of build up of Fluconazole when dosing every day for 10 days so this one dose seams pretty small compared to that. Although I have no idea what the half-life of this is or how long it really stays active in the system.
