Colombo Cytofex

Colombo Cytofex

Colombo Cytofex Anti Bacterial Infections is a great treatment for Hole diseases, Fin rot, Mouth thrush and Dropsy.

Colombo Cytofex is effective against external bacterial infections like skin ulcers, fin rot and hole diseases. Based on 100% natural raw materials, Colombo Cytofex has proven antibacterial effect with the use of Tea Tree oil, extract of Iceland moss and Pau d’Arco-tree.

Hole disease, skin ulcerations, mouth thrush and fin rot are not caused by bacteria but primarily by Cytophaga columnaris (Flexibacter). When the skin is damaged through chafin, fish lice or a disease such as white spot, it opens the fish up to bacterial infections. The infection generally spreads in a circle outward from the damages skin area and round lesions or ulcers appear.

Mouththrush appears aournd the mouth in the form of compact white spots. The fins may be affected by fin rot and take on a shredded appearance. The fish often become listless and if the glls or internal organs become affected death will usually follow.

Cytofex has to be added on 3 consecutive days.

Day 1: 35ml / 1000ltr of pond water

Colombo Lernex
Colombo Lernex

Colombo Lernex

Colombo Lernex Anti Fluke & Worms is a great treatment for Skin and Gill flukes, Piscola and Fish Lice, Anchorworms and other macro parasites.

Skin and Gill flukes are 0.3-0.5mm in size and can only be seen under a microscope.

The skin fluke (Gyrodactylus) gives birth to live young and therefore is capable of fast reproduction. This results in skin irritation and the the thickening of the skin and your fish produce a slimy mucous layer over their skin. Infested fish often rub/flash against ponds walls, pipes, stones etc.

The gill fluke (Dactylogyrus) is a parasite that lays eggs, very similar in appearence to skin flukes, however you can see the eggs (black dots) inside the adult fluke. Gill flukes are found on both the body and gills of the koi. Gill flukes often require 2 doses, one to eradicate the adult, then another dose to eradicate the young. Infested fish often rub/flash against ponds walls, pipes, stones etc.

Colombo Lernex can also work against Macro Parasite such as fish lice (Argulus) which can grow to 1/2 cm, Gill lice, and Anchor worms all of which are visible with the naked eye.

Colombo Lernex is also good for treating Internal Roundworms (Nematodes).
Leeches (Piscicola Geometre) are worm-like creatures with two suckers – a small one which also functions as a mouth and a larger one at the tail end.

Colombo Lernex Dosage:
20g / 500 litres of pond water.
If required, repeat the treatment after 14 days.
