Colombo Morenicol Alparex

Due to regulations, we unfortunately cannot send Colombo products to the United Kingdom.

We advice to order Fish Pharma products ( we can ship Fish Pharma products to UK )


Alparex is active against invisible parasites that cause a gray veil on the fish, such as Ichtyobodo (Costia), Chilodinella, Trichodina and Witte stip.

The presence of these parasites can only be determined under a microscope.

Symptoms of an infestation with these parasites include listlessness, chafing and loss of appetite. When there is a serious fungal infection in combination with the above invisible parasites, Alparex is also a suitable remedy for this.

Application of this drug is at your own risk. Consult the package leaflet before adding to the pond.

Warning: After using Flubendazole, mebendazole and triclabendazole, a 60 day waiting period should be taken before adding Alparex to the water.

After using Lernex and Lernex Pro, the waiting time is 14 days.

Available in:

  • 250 ml.
  • 500 ml.
  • 1 Ltr.
  • 2.5 Ltr.


Extensive info / Instructions for use:

Content calculation:

Calculate the contents of the pond as best as possible: length x width x average depth in decimeters = content in liters.

Water quality:

Good water quality is essential for optimal functioning of Morenicol Alparex and rapid healing of sick fish. Therefore, always test the water quality before and after treatment and correct where necessary. The KH is especially important: it should be between 6 and 8 ° DH before starting treatment.



The Alparex product must be administered in two steps:

1st day: 1 ml per 40 liters of pond water or 25 ml per 1000 liters of pond water.
2nd day: again 1 ml per 40 liters of pond water or 25 ml per 1000 liters of pond water.

A measuring cup is included in the package.

Sturgeons are less tolerant to Alparex in some cases. At the same time, because of their hard skin, sturgeons are also less sensitive to the parasites against which Alparex is active. We therefore advise not to treat sturgeons, but separately with only half the dose (2 days 1 ml per 80 liters of pond water instead of 2 days 1 ml per 40 liters). If necessary, this treatment can be repeated a third time on the third day.

Measure the required amount in the measuring cup and pre-mix with water in a watering can or bucket. Then spread evenly over the pond.

Do not filter over coal or zeolite; Keep UV lamps and ozone devices switched off for up to 1 week after the last administration.



Alparex should not be combined with Flubendazole or related substances. If the pond has been treated with Flubendazole or related substances, observe a waiting period of at least 4 weeks
and change 25% of the water before application. As far as is known, this product is harmless to aquatic animals such as frogs, salamanders, lobsters and snails. If you have positive or negative experiences, please notify us via

Only for use with ornamental fish in ponds. Store between 4 and 32 ° C in the packaging and out of reach of children. Do not breathe. Avoid contact with skin and eyes. In case of ingestion, consult a doctor immediately and show the packaging or label. This product causes permanent stains
on clothing and paving, among other things.



Administered agents will disappear in ponds by natural processes, such as oxidation and breakdown by bacteria.


Pets and birds that drink from a pond with these resources in it.

As a rule, if fish can swim in it, it can be said that it is harmless for animals that only drink from it. Nevertheless, it makes sense to just feed pets dogs and cats accustomed to drinking from the pond during the cure.



There should be a minimum of 2 weeks between the use of Morenicol Alparex and Colombo Algadrex, Lernex, Cytofex and FMC-50. Combinations with other products is expressly at your own risk!


General information:

White spot is caused by Ichthyophthirius multifiliis. This disease mainly has a chance with reduced resistance of the fish, such as after transport, overcrowding, after water changes, after placing new fish and the like. We see white spots of affected fish
0.1 to 1 mm in size, spread or together in the skin. The fish scrape themselves on plants or stones and are sometimes shaking (with pinched fins) in the water. After loss of a lot of (breathable) skin surface, or direct damage to the gills, tightness occurs and finally death.
With real fungus (usually caused by the species Saprolegnia) we see upright threads, a kind of 'cotton wool' stuffing on the skin and / or gills of the fish. The fungus grows superficially over the skin but can also penetrate deeply into muscle tissue and organs, where the damage done eventually leads to death. Itching can be caused by various parasites, for example Trichodina, Ichthyobodo and Chilodonella. Likewise, Gyrodactylus (the skin worm) and the Dactylogyrus (the gill worm), flat suction worms, which grow to 0.3-0.5 mm in size. The mucous membrane of the fish is the main barrier against pathogens. Infestation by one parasite clears the way for another. Often
Several species occur on the skin at the same time, while the problem can also be aggravated by a bacterial infection. Pond fish have the most problems in the spring when the temperature starts to rise. A gray-white layer is formed over the skin due to excessive mucus formation. This is most easily seen on the eyes and when looking diagonally past the fish. The fish also scour themselves. With deterioration we see reddish spots, while the gills swell and the fish breathes faster. Seriously affected fish are listless; they lie on the bottom. Morenicol Alparex contains substances that are very active against the above mentioned conditions. In addition, it has a disinfectant effect against additional bacterial infections. In case of a serious bacterial infection, it is better to work with Morenicol Cytofex. If the itching persists after treatment with Alparex, it is recommended to treat after 2 weeks with Morenicol Lernex or Lernex Pro, a specific agent against skin and gill flukes, anchor worms, fish lice and leeches.

Vorige week al mijn vissen ziek, lagen op de bodem en aten niet meer. 1 koi mee genomen voor een stijkje naar een koi dokter die kon alleen maar witte stip vinden. Op zijn advies FMC-50 van colombo in de vijver gedaan, vissen bleven op de bodem en de volgende dag 2 dode vissen. De koi dokter weer gebeld en die zei dat ik gewoon door moest gaan anders gingen alle vissen dood.
Het zat mij niet lekker al 3 dode vissen, toen heb ik selectkoi gemaild over mijn probleem en ik kreeg gelijk een mail terug met advies om Colombo Morenicol Alparex te gebruiken wel eerst de hele vijver leeg halen.
Ik heb dit gelijk de volgende dag gedaan, en mijn vissen gingen gelijk zwemmen en sinds een kleine week na de kuur eten en zwemmen ze weer gelukkig rond. Als ik dit medicijn niet had gebruikt was ik al mijn vissen kwijt geweest. En ook wil ik koiselect een dikke 10 geven voor hun advies en snelle reactie. Zonder hun was ik sowieso al mijn vissen kwijt geweest.
