Chloramine -T

Size: 20 grams

Usage: Disinfectant (Anti-Bacteria, Fungal, Parasite)

Other name: Tosylchloramide Sodium Salt


Highly water soluble, Chloramine -T is employed as an essential and reliable disinfectant for fish in aquaculture and aquafarming industries. Used for its effectiveness and low toxicity to fish, shrimp and aquatic environments. Chloramine-T is a fungicide, algaecide, antibacterial/germicide, and virucide. All-round disinfectant of tanks and pounds. Can use to disinfect aquarium equipment as well, Chloramine-T ensures that pathogenic microorganisms are rapidly and effectively destroyed by way of oxidation, destroying the bacterial DNA structure. 


Chloramine-T is the safe alternative for traditional and more dangerous chemicals, non-toxic for fish and shrimp at effective dosage and does not leave residues. Chloramine -T is an alternative to potassium permanganate (PP). Extremely effective towards gill disease and fluke parasites.


Chloramine-T is effective against a wide range of microorganisms, including the list below:

  • Furunculosis
  • Marine columnaris
  • Columnaris
  • Flavobacterium branchiophilum (BGD)
  • Vibriosis
  • Hemorrhagic septicemia virus
  • Saprolegnia (fungi)
  • Fungal infections
  • Chilodonella
  • Trichodina
  • Myxobacteria
  • Algae growth
  • Gyrodactylus salaris
  • Ichthyobodo necator (Costia)
  • Ich (white spots)
  • Neopatamoeba pemaquidensis (Amoebic Bacteria Gill Disease)
  • Trematodes (Flukes / Flatworms)





PH and water hardness are the largest impactors of the chemical’s effectiveness – chloramine-t is much more toxic in soft, acidic waters (low alkalinity) (1) and so should be used in waters preferably with a pH of 6.5 or greater and moderately hard or hard water greater than 7°dH (130 ppm), assuming the “hardness” comes primarily from calcium, as calcium carbonate [CaCO3] . If you have soft water, a lower dose will be needed as the chloramine-t will be more reactive.


It’s also not effective if water temperatures are below approximately 11° C (approximately 52° F).

*As with all medication usage, properly aerate the medicated aquarium.


Treatment procedure:

*Caution: Use caution when dosing senstive fish. Chloramine - T will deplete oxygen level, aeration is key when treating fish. We suggest using Chloramine-T as a disinfectant when cleaning aquarium tank and or bath dips when treating fish.  


General Doseage

1 gram treats 100 gallons of water.

Shake 1 gram of Chloramine T along with 1 cup of water in a bottle container before pouring the mix into your aquarium tank. Treatment last 8 days, a second dosage may be recommended for an effective treatment. 


Bath Procedure 

Prepare a 2 mg/L solution. 

  • To achieve this, dissolve 2 grams of Chloramine - T powder to 1 liter (4 cups of water).
  • Place fish in a clean dechlorinated quarantine tank with aeration. 
  • Add 1 mL of Chloramine - T solution (which you've made) to 1 liter (4 cups of water) . This produce a 2 mg/L concentration. 
  • Medicate fish with this solution for 5 hours. 
  • Keep eye on the fish for signs of extreme stress and intolerance. If signs exist, please do 100% water change to remove the medication. Lower dosage maybe required to ensure less stress of the fish. 



Additional Doseage base on water parameter for effectiveness.

We encourage all hobbyist to fully complete the treatment as per directed. Failing to fully complete the treatment by stopping short of the required days, will only fix short term problems and not completely fix the underlying issue. Furthermore, resulting in parasite & bacteria immunity towards the medication leading to more complications.
