Cloverleaf Absolute Wormer Plus – New Pro Strength Formula from Plymouth Discus

Description: Cloverleaf Absolute Wormer Plus is a Flubendazole-based medication, with added pH buffer is the most effective against outbreaks of Gill Flukes (Dactylogyrus), Skin Flukes (Gyrodactylus), Intestinal Helminths (including Tapeworm, Nematodes- “Roundworms”, Planaria- “Flatworms”, Capillaria, Camallanus Nematodes, Metacercaria, Sanguinicola), Hexamita, Anchor Worm (Lernea) and Fish Lice (Argulus). This is a ready-mixed formula for the treatment of internal parasites, worms, flukes and protozoa like Hexamita that affect tropical & cold water fish.

Flubendazole is the effective main active ingredient, & works differently to other Fluke treatments by gently starving the parasite; making this product perfectly safe for regular usage. Naturally sourced Calcium Carbonate is blended in & acts as a gentle booster and ‘pick me up’ after the pests are killed. A minuscule amount of Natural Calcium carbonate (0.01g) is blended with the Flubendazole to adjust a very slight drop in pH from adding the Flubendazole. This cleverly balances out this medication making very little (if any) difference to pH when using wormer plus.

Use when: Fish start to show signs of weight loss although maintaining a healthy appetite. Fish may appear lethargic with loss of colour. Often fins remain clamped, and they may flick/rub. They may also spend unusual amounts of time at the surface.

Cloverleaf’s Pro-strength formula rapidly reduces gut parasite burden on fish in fresh water. Discus had a bad name as a difficult fish to keep, some said imposable. NOT SO, just misunderstood. As long as they have the right conditions & free of parasites they are just as easy to keep as any other tropical fish.  Discus keeping in the old days was regarded as a fish shrouded in mystery, and difficult to keep. Just to be kept by the experts and the highly experienced. It is recommended to worm your discus once a month for trouble free discus keeping and this will give them a flying start if introducing new stock. Now keeping your favourite tropical fish has never been easier.

We highly recommend to treat Discus and other aquarium fish once a month with Cloverleaf Absolute Wormer Plus to keep your valued Discus & fish in tip top health.
