If you can get MB I would use that. Use at double in tank dosage in a 5 gallon bucket of tank water. Bath the fish for 30 mins. Once a day for 7 days. To the bath add 2 tablespoons of aquarium salt. While the fish in in the bath do a 50% water change in the main tank, this is important. The tank water must be clean.
Pops was giving you good advice, I'm just expanding on what he suggested.
The MB i can get isnt pure, it is:
Im in australia, and methylene blue is very hard to get pure... the only thing i can get is:
http://www.thetechden.com.au/Blue_Planet_Multi_Cure_500ml_p/el052.htm
and it has:
Malachite Green 0.40mg/ml
Methylene Blue 4.00mg/ml
Acriflavine 2.00mg/ml
Dose rate is 0.25ml per Litre, 5g Bucket is 18L @ double dose rate would be 18 * 0.5ml = 9ml in the bucket with the fish.
Would you advise on the metro food soak as pops suggested?
Also as a side note, what do you suggest for the dose rate with Potassium Permanginate? I have been told so many different things!!
what i have been advises is 1g to 1L tank water, mix in a bottle, then use 25ml of that solution in 5L of water and put the fish into the 5L....does that sound correct?
Thanks
