I bought my Chloramine T in SA..There it is used as prophylactic pond treatment in spring and summer.
Also when frequent ulcers and other bacterial diseases is used as pond treatment.
Basically it is a disinfectant…
This is what I was given when I bought it. I hope it helps. So far I have used it on my fry a week old and had good results.
I know people that use it as dip too.
Chloramine-T (n-chloro-para-toluene sulfonamide sodium salt) like most other koi medication that we use in bulk, is also used extensively for many other purposes. The uses include treating water plants, aquatic bio security, dental hygiene as well as a disinfectant for pig-, poultry-, and cattle farming, cooling towers and for veterinarian use. It is also used for disinfecting ion exchange resin.
The dosage when treating a pond is very dependent on the alkalinity of the water, as well as the dissolved organic content.
pH
Water hardness below 80
Dosage
Water hardness above 80
Dosage
2.5 g per 1000 litres
5 g per 1000 litres
5 g per 1000 litres
7.5 g per 1000 litres
8 g per 1000 litres
10 g per 1000 litres
At the above dosage, the impact of Chloramine T on the nitrifying bacteria in a filter system will be negligible.
Chloramine T can also be used to sterilise nets, bowls, feeding troughs and water containers. The normal requirement for a sterilizing agent is speed and safety. In such an instance a dosage of 20 g per 1000 litres will be applicable.
When Chloramine-T is dissolved into a water body like a pond, it slowly breaks down to produce hypochlorous acid (HOCl), which in turn releases chlorine and oxygen.
One word of caution though, the simultaneous use of Sodium Theosulphate will instantly neutralize the Chlorine and render the treatment useless.
Please note
Chloramine T is not recommended as a high dosage dip for koi.
Chloramine T is safe to use in a pond with a normal therapeutic with salt content.
Aerate the water during treatment
The breakdown of Chloramine-T is speeded up in sunlight, so treatments are best carried out during the late afternoon
UV lights should be switched off during treatment
