Description

NT Labs Methylene Blue 100ml

NT Labs Methylene Blue 100ml is a classic aquarium treatment for bacterial, fungal and some external protozoan parasitic infections in fish, fry and eggs. It suits both coldwater and tropical set-ups, making it a practical fish medicine for breeders and everyday keepers to have on the shelf.

Key Benefits

  • Targets bacterial, fungal and certain external protozoan parasitic infections
  • Can be used for fish, fry and eggs, so it is useful in breeding set-ups
  • Works in coldwater and tropical aquariums
  • Flexible: use it as a treatment bath, in a quarantine tank, in the main aquarium, during transport, or dabbed directly onto wounds

When to Use It

Reach for Methylene Blue when you notice any of these signs:

  • Fluffy, cotton-wool-like fungal growths
  • A grey, velvety film or excess mucus over the body
  • Bacterial damage such as red open wounds, ulcers, missing scales, rotting fins and eroded mouth tissue

It is most effective in a quarantine tank or treatment bath. It can also be added to the main aquarium, used to protect fish during transport, or dabbed undiluted onto wounds with a cotton bud.

How to Use

  • Work out your tank volume.
  • Shake the bottle well.
  • Mix the required dose into a litre of aquarium water.
  • Add the mixture to the tank slowly.
  • If needed, repeat the dose four days later.

Dosage

  • Tank treatment: roughly 10 ml treats 90 litres.
  • Quick dip: 2 ml per litre of fresh dechlorinated water. Immerse the fish for no more than 10 seconds.
  • Wound treatment: dab undiluted onto the affected area with a cotton bud.

Important Notes

  • Methylene Blue can harm live plants and shrimp if overdosed.
  • It will affect the beneficial bacteria in your biofilter. Remove carbon during treatment, keep filtration running, and follow up with a 25% water change afterwards.
  • It stains skin, silicone and ornaments, so handle with care.
