Review: Quality treatment - One of my koi had developed a nasty infection. It's body was covered, and one fin was very red, looked as though it was rotting. And no it wasn't koi pox. Have to say after the second treatment, very nicely recovered. Throughly recommend.
Review: Excellent result - The product did what the label said it would so would recommend product.

## Features

- 【 ANTISEPTIC AND ANTI-BACTERIAL TREATMENT FOR KOI 】: Use when fish show symptoms of a bacterial infection, or as a quarantine solution before adding new fish.
- 【 TREATS FIN, TAIL & MOUTH ROT AND ULCERS 】: A powerful antiseptic, anti-bacterial treatment for mouthrot, tailrot and finrot. Acriflavin can also be used in conjunction with NT Labs Ulcer Swab and NT Labs Propolis Wound Seal for the treatment of ulcers and other open wounds.
- 【 EASY TO USE 】: To work out the required dosage for your pond, simply calculate the volume of your pond in litres (length x width x depth (in cm)/1000) or alternatively, use our Online Dosage Calculator. Mix the appropriate dosage in a clean bucket of pond water, pour evenly over the surface of the pond and leave for 7 days. Switch off UV filtration until the colour has gone from the water. Aerate the pond well during treatment. If you feel a repeat dose is necessary, check your diagnosis using the Diagnosis Tool; a different medication may be more suitable. Allow 7 days after medicating and perform a partial water change before re- treating or treating with a different medication.
- 【 EFFECTIVE ACTIVE INGREDIENTS 】: Koi Care Acriflavin contains Acriflavine neutral (80 mg/100ml). This ingredient makes it a powerful solution to treat bacterial infections in koi.
- 【 THE LEADING RANGE OF KOI CARE PRODUCTS 】: The most highly regarded range of koi products in the industry, trusted for 40 years by both trade customers and consumers alike, this range effectively cares for and protects koi in the environment in which they live. From products that treat parasitic or bacterial infections to a tap water dechlorinator, the NT Labs Koi Care range offers koi enthusiasts everything they could possibly need to keep perfect koi and an equally perfect koi pond.
