I have recently used Acraflavine. I seemed to of read conflicting ideas on the dosages to use. so I would be interested to know what rate any of you guys use it at. My tank is 220L or 46G. I used 20ml what amount would you say to use in that size tank. Also I have recently read Paul and Slackey recommend Salt at 200G per 100L. This is something else I may have got wrong I put 200G of salt with the Acraflavine which is half of what I should of used for my tank. The reason I need know is I lost a fish with an injury I think I should of been able to save and it is really bugging me now because i may have underdosed. I just want to make sure I have got this right for the future. Thanks for any advise Guys.

Salt is the easy one to answer. When used as a support to aid osmoregulation etc then the dose is 100 grams / 100 litres. When used as a treatment then the dose is a minimum of 200 grams / 100 litres. I have gone up to 300grams / 100 litres before. Acriflavine is a flexible med, and this has possibly been it's downfall. The usual recomendation is to dose as per the manufacturers dosing rate. However when it used to be made up from a powder it would be dosed in anything from 1ppm to 5ppm (parts per million or mg/litre). Full theraputic dose is 3 to 5mg/litre (3 to 5ppm). Some brands tell you how much acriflavine their liquid contains (Kusuri for example is 1%) so it is a case of doing the math.

:°° paul, so how would you work that out if you had a 1% acriflavine solution ? not sure how you would convert that to ppm.

ok the salt is in my note book now so understand what i am doing. as for the acraflavine you guys are to clever for me i am lost

dane, yeah got that now, long time since i had to have my maths head on . so that gives you the ppm of the product. then correct me if im wrong, volume of tank water divided by volume of dose = x then ppm of product divided by x gives you the ppm you will have in the tank ??? :°° think thats right. if im correct i have some acriflavine @ 0.2 % the dose for 750 litres is 10ml. so this is a 2.6ppm dose rate ? so i could double this dose if wanted ?

Ok then one last attempt! can anyone tell me what they think the correct amount of Acraflavine should be in a tank of 210L

Really depends on the brand Paul. I use Kusuri Acriflavine and for a 210L tank the recommended dosage is 4.6ml, to be practical I would add 4.5ml. To get accurate dosages to administer use a baby/infant oral medication syringe from the chemist (they are free) they have 0.5ml gradients

God!! Ive gone a bit overboard with it then, 20ml, mind you the fish were ok i think its tap that i used. Thanks Slackey, ps got one of them syringes of Steveo

Well depending on what dose rate of acriflavine you want depends on how much liquid you add. If you want 1 ppm (equivalent to 1mg/litre) then to dose a 220 litre tank you would need a total of 220 milligrams of acriflavine, for a 2ppm rate then 440 milligrams and so on. @1% solution 1 mil contains 0.01 gram or 10 milligrams. So from here it is easy to work out how many mils we need to dose the tank. For a dose rate of 1ppm we need tank volume divided by millilitre content (in milligrams), so 220 / 10 = 22 mils. Hope that helps.

Anyone know the strength of the 'Kockney Koi Yamitsu, Acriflavine' Nothing on the bottle except 1ml per 75l
