Lernex 800g/20 000L

Lernex is active against skin worms (Gyrodactylus), gill worms (Dactylogyrus), and internal worms (Nematodes).

The presence of these parasites can only be determined with a microscopic examination.

Lernex is also an effective treatment against leeches (Piscicola), sea lice (Argulus) and anchor worms (Lernea); these parasites are visible to the naked eye.

Sufficient for :
200 g = 5.000L
400 g = 10.000L
800 g = 20.000L
2.000 g = 50.000L

Recommended use :

• First determine what type of parasite you are dealing with: you can do this by eye for leeches (Piscicola), lice (Argulus), and anchor worms (Lernea); skin worms (Gyrodactylus), gill worms (Dactylogyrus), and internal worms (Nematodes), on the other hand, require microscopic examination.
• Always use Lernex as the first line of treatment, and only if the microscope shows that the treatment is not effective against skin and gill worms, then use Lernex Pro.
• Use Lernex Pro with care, and use Lernex Classic again for the next treatment.
• Make sure you have good water quality and strengthen the immune system of your fish with good nutrition. This way you prevent worm resistance to Lernex Pro.
