Evaluation of your pond volume: Calculate the pond water volume by
as precisely as possible: length x width x average depth in decimeters. You will get the volume in liters. Morenicol Lernex is available in: 250
ml for 5,000 ltr, 500 ml for 10,000 ltr, 1 ltr - 20,000 ltr and 2.5 ltr - 50,000 ltr.

correct the values if necessary.

Dosage: Dosage: 20 g (=1 scoop) per 500 liters of pond water. The scoop
is included in the packaging. If necessary, the treatment can be repeated
after 14 days. Parasites of cold-blooded fish. This means that at lower temperatures, their metabolism decreases. Below 10°C Lernex is not
sufficiently absorbed by the parasite.

Mix the product with water from a bucket or watering can. Then distribute the mixture
throughout the pond water. Do not filter with charcoal or zeolite; UV lamps and
the equipment must be unplugged up to 1 week after administration
8 of the treatment. Thoroughly clean the mechanical and recirculation filters if present before the treatment and leave them connected during the treatment, to
so that the larvae are also removed in the filter.
Catabolism: Remedies administered in the ponds will disappear by themselves thanks to natural processes such as oxidation and decomposition
by bacteria.

Information: Gill lice (Argulus) can reach a size of up to ½ cm.
They are flat and round, and have many legs on the side of the belly. Using
with 2 suckers, they attach to the fish and pierce its skin using the part
venomous from their mouth. They feed on the moisture of their skin
host; it loses weight and rubs against the bottom of the pond and plants. The argulus
drops its eggs into the water.

These eggs then turn into larvae, which must find a fish within one day to survive. Below 14°C, there is no reproduction, which means the problems mainly occur in summer. Gill lice (Ergasilus) are smaller. They attach to the 9 gills and eat them. The gill tissue can then become infected. In any case, the gills start to swell. The fish suffocate and can even die.

This most often occurs in July and August. Lernea can measure a few centimeters. They are not worms; they belong to the family of parasitic crustaceans. They mate on the gills. After that, only the females become harmful. They attach to the fish and pierce it with their anchor-shaped head. The first symptom is bleeding in the fish's skin, visible as a small red spot on the skin.

When the parasite is adult, their body, containing 2 egg sacs (like a V), protrudes from the fish and is visible and dragged in the water. When these sacs fall off, they leave behind a disgusting pustule. From these eggs hatch small larvae that contaminate the gills again. 

Gyrodactylus and Dactylogyrus. These are flat sucking worms 0.3–0.5 mm long, which were once very rare in our ponds. Today they are regularly detected. Gyrodactylus is a viviparous skin worm that reproduces quickly and in large numbers.

Its passage on the skin causes swelling and leaves a viscous gray layer. The gill worm is called Dactylogyrus. It damages and irritates the gills, causing swelling and poor gill function. Fish rub their gills against plants and stones. When it worsens, they swim with open gills.
to avoid asphyxiation and can even die from it.

Internal worms (Nematodes) generally belong to the nematodes or roundworms, which are found in the intestines. The larvae from the eggs are also transferred by live food. There are larvae that travel throughout the fish's body and can be stored in muscle and organ tissues. From these dormant larvae, adult worms form under certain conditions. Fish severely affected by nematodes lose weight and have slimy stools.

Leeches (Piscicola geometra) are small worms with 2 suckers: one
small one that also serves as a mouth and a large one at the tail. They
have a transverse line and are on average 2-4 cm in size. Thanks to the
tail sucker they attach to stones or plants and wait for a
fish passes to jump on it in a fraction of a second and they attach
to it thanks to their oral sucker.

Like any other parasite, they can cause infections. They cause agitation and rubbing in fish. If they are very numerous, the fish are literally drained and die. All of these parasites cause wounds in the fish's skin, which can become infected by bacteria and molds. It is advisable to treat with Morenicol Cytofex or Morenicol FMC-50.
