First do a 20% water change. Use One 200mg capsule per 10 gallons. I opened each pill and poured the fulconazole into a 3/4 filled water bottle. Throw away the empty capsule. Close the cap and shake the bottle to disolve everything. Turn off your skimmer, take out your carbon, and turn off your UV if you have one. Pour the fluc over a powerhead so it gets spread out evenly thru your tank. You should see improvement after about a week. After 2 weeks it should be all gone. Do another 20% water change. If GHA is still present, repeat another cycle. Good luck!
