  Quickly and easily monitor ammonia levels in your koi pond with Colombo’s NH3 Ammonia Test Kit. This liquid reagent test allows accurate testing of total ammonia to ensure a safe, healthy environment for your koi.

  Ammonia is extremely toxic to fish, even at low levels. Goldfish and koi ponds must maintain ammonia below 0.02 mg/L. Higher concentrations burn gills, suppress the immune system, and can be fatal.

  The Colombo test kit contains everything you need to measure total ammonia. The kit includes detailed colour-coded charts, ammonia test reagent, and plastic glass vials.

  To test, simply fill a vial with 10ml pond water and add 5 drops of each reagent. Shake to mix, wait and compare against the colour chart to determine ppm of ammonia present. Rinse vial between tests. 

  Catch ammonia spikes before they harm your fish. Colombo’s Ammonia Test Kit is trusted by koi keepers for fast, accurate testing anytime. Order today and keep your pond water safe.

  Colombo FMC-50

  Colombo FMC – 50 is an effective koi treatment against white spot and fungus.

  White spot is caused by lchtyophthirius multifiliis. This disease usually occurs when the natural resistance of fish is reduced or compromised. Examples of such circumstances include transportation overcrowding, water changes or the addition of new fish.

  Affected fish show white spots on their skin, approximately 0.1 to 1mm in size. These spots can be separate or clustered. The fish chafe their skin on plants or rocks and sometimes ‘rock’ back and forth in the water. After loss of the use of their (breathing) skin surface or when the gills are affected, shortness of breath sets in and eventually the fish will die if the correct koi parasite treatment is not used.

  Dosage:
  

  • Colombo FMC50-Anti White Spot 250ml – Treats 6,250 litres
  • Colombo FMC50-Anti White Spot 500ml – Treats 13,000 litres
