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.

Start with a 30% water change. Will work if you catch it early
We had an outbreak of white spot and I could tell it wasn't good. I ordered this and got it next day. A quick normal water change (in hindsight I should have done a 30% at the start). You then add a dose of this every 2nd day i.e. Mon wed Fri. It's easy to use and dosed at 10ml per 200 L of your tank. Unfortunately I did lose a lot of fish because it was too far developed but some did recover. If you start using this we early there is a good chance of recovery.. after the 1st week of treatment I did a 30% water change and it settled down. Make sure you remove any dead for sh asap Good quality and value. To recommended. Thank you for reading my review.i hope you found it useful.

Super efficient
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.

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
