Treatment with OTC and Copper Sulphate
It is very effective combination for treating discus fish, covering quite a wide range of fish diseases, especially discus fish. It kills parasites and bacteria internally and externally.
The dosage and duration of treatment is important. Otherwise most of time you will be very disappointed. But it is very effective 100%
Preparation of copper solution:
6.5 grams /1 liter of still water
Treatment: Tank of 100 liters of water
- 3ml of copper solution
- 1 small spoon of Oxytetracycline (OTC). Spoon Measurement – We use Kentucky Fried Chicken small spoon
Must change water everyday. Repeat the treatment for at least 1 week. No feeding after water changed. Feed them before water changed, if you want to.
