## Description

Aquarium Anti-White Spot and Fungus

Review: Good product and decent price
Review: Maravilloso y efectivo - No pensé que iba hacer efecto tan rápido al segundo día de aplicación se empezaron a desaparecer los puntos blancos de mis tretas, tuve una infección de punto blanco en mi acuario muy pero muy fuerte, los peces se me morían al día siguiente que se les empezaba a ver el punto blanco, algunos de un día para otro se brotaban de puntos blancos por todas partes, perdí 4 escalares y de 10 tretas solo uno me sobrevivió y eso gracias a este producto y su rapidez de acción. Ojo: el uso hay que saberlo usar y está en inglés así que te traduzco. Se debe usar 5ml por 100 litros de acuario, si tu acuario es más pequeño pues sacas por regla de 3 los ml que necesitas, en mi caso acuario de 60 litros le aplicas 3ml, un día sí y el siguiente no y sigues así hasta completar 7 días de aplicación del producto, así tus peces si hayan curado el parásito sigue en el agua y hay que eliminarlo totalmente. El medicamento te pinta el agua de azul oscuro pero es normal no hay que asustarse a las horas vuelve a estar igual de cristalino que antes. El medicamento es extremadamente fuerte tienes que usar la dosis precisa según los litros de tu acuario para no pasarte, yo compré unas inyectadora y con ella le aplico la cantidad justa, ya que tengo acuarios de muchos tamaños y unos de 22 litros que llevan dosis de 1,2ml

## Features

- 【 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.
