Colombo Lernex Pro 1000ml
Colombo Lernex Pro 1000ml £69.99 £79.00
Lernex® Pro is an optimised version of Morenicol Lernex, developed for the treatment of resistant skin and gill worms in ornamental fish. Lernex® Pro is based on the latest scientific knowledge and contains high-quality anthelmintics against which no resistance has yet built up. Lernex® Pro is therefore highly effective in the treatment of resistant skin and gill flukes. The presence of these parasites can only be determined under a microscope. Effective against: Resistant worms (flukes) Skin Worm Gill Worm Water quality: For an optimal effect of the treatment and for a quick recovery of the diseased fish, a good water quality is essential. Hence, always test the water quality before and after the treatment, and correct when necessary. Dosage: 1 ml (1.25 g) per 20 litres of pond water. The required amount of Lernex Pro can be measured using the 15 ml measuring spoon supplied (18.75 g). This amount should be slowly poured into the pond water in a place with a strong current, e.g. the outlet of the pump or filter. Ensure good aeration so that your fish have sufficient oxygen at all times. Do not filter through charcoal or zeolite; keep UV lamps and ozone devices switched off for up to 1 week after administration. This veterinary medicine must not be overdosed; adhere to the dosage instructions. The eggs of the worms are not killed by this veterinary medicine. Therefore, the treatment should be repeated after 14 days to kill these larvae and prevent reinfection. This 14-day period is not dependent on the water temperature. 1000ml bottle will dose 20,000 litres 
Colombo Alparex 1000ml
Colombo Alparex 1000ml £59.99 £67.00
Alparex is effective against invisible parasites that cause a greyish bloom on fish, such as Ichtyobodo, Chilodinella and Trichodina. In addition, White spot and Fungus are effectively treated as well. Effective against: Invisible parasites White Spot disease Fungus Water quality: For an optimal effect of the treatment and for a quick recovery of the diseased fish, a good water quality is essential. Hence, always test the water quality before and after the treatment, and correct when necessary. The KH-value is especially important as this should be between 6 and 8°DH, before the treatment is started. Dosage: Alparex has to be administered in two steps: 1st day: 1 ml per 40 litres of pond water, being 25 ml per 1.000 litres of pond water.  2nd day: again 1 ml per 40 litres of pond water, being 25 ml per 1.000 litres of pond water. A measuring cup is included in the box. Sturgeons may have a reduced tolerance to Alparex in some cases, but their hard skin also makes them less susceptible to the parasites that Alparex treats against. We thus recommend that you do not treat sturgeon together with the other fish, but instead treat them separately with only half the dose (two times 1 ml per 80 litres of pond water instead of the usual two times 1 ml per 40 litres). If needed, a third dose on the third day can be administered. Measure the necessary amount in the measuring cup and mix with water in a watering can or a bucket. Distribute evenly over the pond. Remove carbon and zeolite during treatment; UV-lamps and ozone should be switched off during 1 week after the last administration. Warning: Alparex cannot be used in combination with Flubendazole or related substances. Wait at least 4 weeks and change at least 25% of the water before using Alparex if the pond has been treated with Flubendazole or related substances. As far as known, this product is harmless to aquatic creatures such as frogs, salamanders, freshwater lobsters and snails.

Store in the box at a temperature of 4 to 32°C. Do not inhale. Prevent contact with the skin and eyes. If swallowed, immediately consult a physician and show package or label.

Fluke-Solve 100g
Fluke-Solve 100g £54.95
Unlike Fluke-Solve Plus, standard Fluke-Solve can be used in a wide range of fish including Koi Carp, Sturgeon and Goldfish. 100g pack - Suitable for treating 25,000L (5,500 gallons) Fluke-Solve is: Easy to use – it dissolves readily without having to use boiling water or solvent Safe for the fish and for other creatures in the pond or aquarium Economical Science based data to confirm the efficacy of the medication. Contains 50% praziquantel Fluke-Solve® contains 50% praziquantel, and its unique rapidly dissolving formulation means you can see it dispersing through the water as soon as you add it to your pond or tank. It successfully treats skin and gill flukes (Monogenean species), eye flukes (Diplostomum species) and intestinal tapeworms, even by immersion, and can be used in a wide range of fish including Koi Carp and Goldfish. It is suitable for both freshwater and marine systems, including in the presence of salt when added as a therapeutic, and is even effective from 3°C. Fluke-Solve® is safe with biofilters and plants, as well as shrimp, snails and frogs, and can even be used to treat parasites on shrimp. Flukes belong to the group of parasites known as  Monogean trematodes. The most common kind affecting pet fish are the Dactylogyrus and Gyrodactylus species. Cestodes or tapeworms are internal parasites which affect a wide variety of fish species including Koi Carp, as well as aquarium fish such as discus.  How to use/dosage  Use at a rate of 4g powder per 1,000 litres (220 gallons) of pond or tank water. Simply take a clean container of the pond or tank water and add the required dosage of Fluke-Solve® to it, then stir. Immediately add this stock solution to the pond or tank, and then rinse out the container with the pond or tank water and add that as well. If necessary, a separate tank can be used to treat the fish for a treatment period of at least 24 hours. Take care to turn off skimmers while it is in use since they will remove the praziquantel from the water, as will modern filtration systems which use carbon derivatives, or some drum filter technologies. The praziquantel in Fluke-Solve® will persist in a pond or tank for at least 3 weeks, so in the case of some egg-laying flukes repeat the initial dose after 3 weeks to ensure the active ingredient is in the water long enough to kill any hatching fluke larvae and break the cycle of infection.  
Fluke-Ex 100g Fluke-Ex 100g
Fluke-Ex 100g £54.95
FLUKE-EX® is a new unique product developed by Fish Treatment Ltd for use in ornamental ponds or tanks, with a number of benefits compared with existing products. It has been priced to give significant savings. Efficacy has been demonstrated by extensive clinical trials to confirm it treats skin and gill flukes including all the resistant strains of flukes (where other treatments have failed) but it can also be used to treat Trichodina, Costia, tapeworms, roundworms and crustaceans such as Argulus (fish lice). It can be used in the presence of salt. It uses the same proprietary technology as the Fluke-Solve range so the method of administration is the same – simply rip, tip and stir. However in the case of gill flukes which lay eggs, as with previous products a second treatment is recommended after 3 weeks to break the flukes’ life cycle. The product is now indicated specifically for use in Koi ONLY. While Fluke EX may be suitable for use in other fish species, such use should only be undertaken under the guidance and supervision of a veterinary surgeon to ensure the safety and well-being of the animals. It is effective from temperatures from 3c. Simple to use, safe and effective.

Aqua-Sed
Aqua-Sed £19.99
Description  Aqua-Sed is based on the tried and tested active ingredient 2-phenoxyethanol, and it comes in a 250ml bottle with an easy-to-use measuring pump. It's a liquid with a very wide safety margin and has been used for anaesthetising fish for many years (reports go back to 1943). Please note that any anaesthetic a carries a risk, sometimes because the fish may have an unknown/undiagnosed problem which may cause an issue. For this reason we do not suggest the routine use of anaesthesia of koi carp for a general check-up.   How to use/dosage The dose is dependent on water volume, not on fish size. Do not put Aqua-Sed™ into the main pond or tank, it is for use in small volumes once fish are captured. Using the pump, measure the required amount into water (1 pump/litre) into a suitably sized anaesthetic container. Gently mix the slightly oily liquid into the water. Transfer the fish into this solution and observe carefully. Some initial excitement is normal in some species. The fish itself pumps the drug across its gills, administering the dose until effective. Observe the fish throughout and remove the fish when it is suitably anaesthetised for the procedure. As a general guide, gill cover movements should be slowed but not completely stopped. Following the procedure return the fish to untreated water for recovery.   Q. What temperature should the water be when using Aqua-Sed?A. Aqua-Sed will work in water of all temperatures and there is no minimum temperature it can be used at. At lower temperatures it will take longer to take effect, so please be aware of this.   Q. How should I store Aqua-Sed?A. Aqua-Sed should be stored at room temperature to prevent the liquid from becoming too thick to mix with the water.       Q. Can I use Aqua-Sed to sedate amphibians?A. Yes, you can use Aqua-Sed to sedate amphibians at the same dosage as stated for fish, However great care should be taken and under veterinary supervision as the process will take effect much quicker due to the product being absorbed through the skin.
