Review: Good product and decent price - I used the NT Labs Anti White Spot & Fungus treatment when a couple of fish in my tank started showing those classic tiny white spots, and overall it did a good job clearing things up. The dosing schedule was easy to follow, and I appreciated that it didn’t seem to harm my plants or filter system while it worked. The water did turn a bit green during treatment, which wasn’t ideal for aesthetics, but it cleared up a few days after finishing the course. Most importantly, my fish looked much healthier and more active after the treatment — so for the price and ease of use, I’d say it’s a solid choice for dealing with common freshwater ailments.

## Features

- May cause an allergic skin reaction.
- May cause cancer.
- 【 WHITE SPOT TREATMENT 】: White spot is a protozoan parasite; the adults live on the fish and appear as tiny white spots. The adult has a complex life cycle which results in hundreds of free-swimming juveniles looking for a host fish to infest. Combat white spot and fungus in your aquarium with our specialised Aquarium Anti-White Spot & Fungus solution, containing two active ingredients - Malachite Green (140 mg/100 ml) and Formaldehyde (800 mg/100 ml).
- 【 RELIEVES FISH FROM IRRITATION 】: Easily identify when to use the treatment by observing small white spots resembling grains of salt on your fish. If your fish show signs of irritation, rubbing against objects, exhibit a grey, velvety film or have white cotton wool-like growths on their body/mouth/ fins, our treatment is the perfect solution.
- 【 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 and mix required dose of treatment with 1 litre of aquarium water. Add slowly to aquarium. Changing water between doses is not recommended, except in an emergency. Follow these simple steps for optimal results.
- 【 7-DAY COURSE OF TREATMENT 】: Designed as a 7-day course of treatment, our powerful solution efficiently targets protozoan parasites, providing comprehensive relief for your fish. Adding the first dose to the aquarium is day 1. Repeat the dose on days 3, 5, and 7. After the 7th day, wait 7 days before a partial water change. Repeat or use another medication as needed, following the same dosing schedule.
- 【 NON-TOXIC TO SNAILS, SHRIMP AND FISH 】: The concentration of the product is non-toxic to snails, shrimp and fish, etc. All of the medication in our Aquarium range are formulated with sensitive species in mind. There's no need to use half doses, but if you think you have a particularly sensitive fish, you can always give the treatment as two halves given throughout the day. The solution will colour the water green but this should fade within a few days of the final dose being added.

*by S***R on 20 January 2026*

In just 5 days of treatment all fish were cured . Not one white spot left on them . 0 loss and they haven't been stressed at all . I have a 400l I followed dosage to treat a 300l as I got some fragile fish and also fry . Still have 1 treatment to make and it will be the end of the 7 days . This product is brilliant.
