Quick Summary
NT Labs Aquarium Anti-Ulcer & Finrot is a 100 ml aquarium treatment for bacterial infections linked with finrot and ulcers. It is described as containing acriflavine and as treating bacteria such as Aeromonas and Pseudomonas. The pack is stated to treat up to 500 L, so the treated volume is an important check before use.
The product is also described as suitable when fish have red wounds, ulcers, missing scales, red blotches, rotting fins or eroded mouth tissue. It is intended for aquarium use and the dosage is linked to the water volume in the tank.

What to Compare Before Buying
- Aquarium volume: The pack is stated to treat 500 L, so confirm the tank size before choosing an offer.
- Target problem: This treatment is aimed at bacterial infection signs linked to finrot and ulcers, rather than general aquarium care.
- Active ingredients: Check that the ingredient profile suits the exact treatment you want to use.
- Water change timing: The water may turn yellow after dosing, and the text says to wait until the colour has faded or at least 5 days before water changes unless there is an emergency.
How It Works
The treatment is added to aquarium water after the dose has been measured for the tank volume. The bottle should be shaken thoroughly before use, and the required dose is mixed with 1 litre of aquarium water before being added slowly to the aquarium.
The product is described as colouring the water yellow during treatment. It is also stated to be harmless to filter bacteria, fish and plants.
Before You Decide
Check the aquarium volume, the fish symptoms you want to treat and the stated pack coverage before you buy. Follow the dosing instructions on the bottle carefully, and follow the manufacturer instructions for any water changes or repeat treatment.
