## Features

- 【 POWERFUL CONTROL OF SKIN AND GILL FLUKES AS WELL AS INTERMAL WORMS 】: Fish (especially Discus species) are susceptible to internal worms. An obvious sign is when fish become very thin but continue to feed. Aquarium Anti-Fluke and Wormer is formulated to be used when fish become lethargic, fins are clamped, thin looking, gasping and showing signs of rubbing/irritation.
- 【 EFFECTIVE ACTIVE INGREDIENT 】: Aquarium Anti-Fluke and Wormer contains Flubendazole (1000 mg/100 ml). This ingredient makes it a powerful solution to eradicate flukes and internal worms. Caution, this product contains flubendazole and will kill snails, shrimps and other invertebrates.
- 【 EASY TO USE 】: Simply calculate the volume of your aquarium in litres (length x width x depth in cm/1000) or use the NT Labs online Dosage Calculator. Shake the bottle thoroughly before use, increase aeration in the aquarium to maximum, use the pipette provided to add the required dose. The treatment can be repeated once a week up to 4 doses. Following these steps will allow you to maintain a healthy aquatic environment effortlessly!
- 【 HARMLESS TO FILTER, FISH AND PLANTS 】: While our Anti-Fluke and Wormer solution can occasionally turn your water cloudy, rest assured it is harmless to the filter bacteria and all species of fish and plants. If the water becomes cloudy, change 50% at a time until the cloudiness goes away.
- 【 PRAISED BY EXPERTS 】: Aquarium Anti-Fluke and Wormer has earned recognition for its effectiveness in treating flukes and worms. It has been endorsed by aquarists, such as Fish Shop Matt, and Practical Fishkeeping Magazine's Associate Editor Nathan Hill.

**Q: Is it harmful to bio filter?**
A: No. but will kill shrimp and possibly snail if you use enough of it

Good

### ⭐⭐⭐⭐ Not sure this works
*by A***N on 21 March 2019*

Doesn’t kill free swimming worms in the tank so don’t expect it to kill worms in the fish. Never had any impact on the fish so don’t believe it works.
