For treatment of praziquantel-susceptible disease conditions in ponds. Liquid PraziPro is a ready-to-use, liquid concentrate that was developed to offer an effective way to control unwanted parasites in ponds. Extremely safe and super effective this revolutionary product offer you rapid control yet will not negatively impact your biological filtration. Applied at a rate of 1 ounce per 200 gallons. Hikari PraziPro liquid is available in 16 oz bottles and 1 gallon jugs.
AS A BATH: Start treatment with as large a water change as practical or start with new water. Any new water used should first be conditioned to remove ammonia, chlorine and chloramines. Do not stop filtration, but remove activated carbon and stop foam-fractionation (protein skimming) and UV sterilization.
Application Rates & Dosages
Measure Pond Solutions Liquid PraziPro at the rate of one (1) teaspoon per 32 gallons of water to be treated. (one (1) fl. oz. per 200 gallons) This produces a concentration of 2.5 mg/L. Distribute the proper amount around the edge of the pond or directly in to the filter box to achieve the best overall distribution. A single treatment lasting 5-7 days is normally sufficient. Repeat as necessary, but no more than once every 3 to 5 days. May be used as a preventative, at the standard dosage, when disease is likely. Do not use with other drugs or disease treatments. May cause temporary foaming.
RECOMMENDATIONS: Use Liquid PraziPro any time unwanted parasites are noticed or introduction is probable.
CONTENTS: oxybispropanol (as an inert solubilizing agent) and <5% praziquantel by weight.
Skin Flukes or Gill Flukes in Koi
These are common worm like parasites (or ectoparasite) about 1-2mm in length which live in and reproduce in the gills of cold water or tropical fish (occasionally on to the surrounding skin). Due to their small size they are hardly visible.
Indeed it is sometimes said that "Flukes are to fish as fleas are to dogs". Many aquarists treat for flukes on getting any new fish as a matter of routine.
They are called monogenean trematodes, which describes their biological classification (trematodes) and the fact they only need one host to complete their life cycle (monogenean).
A gill fluke has a series of hooks on its body and uses them to attach and drill into the flesh of the fish via the gills. This leaves holes in the flesh which can be lead to secondary infection by bacteria. But the flukes also reduce the ability of the fish to take in oxygen and if the flukes multiply then the fish becomes listless and dies of either a bacteria infection or oxygen starvation. Usually very quickly indeed.
Initially you'll see rubbing and flashing of the fish. Heavy infestations are life threating as bacteria and fungus infections often occur. As the parasite reaches a more advanced stage the fish will become lethargic. As the parasite multiplies the fish will isolate itself and spend long periods laying on the bottom with its fins clamped to its body or simply keeping to a corner of the tank.
Often you'll see rapid breathing, loss of appetite, discoloured gill filaments, and swollen gills. Infected fish may also gasp at the water surface where the water has a higher oxygen concentration or lay at the bottom due to the gill damage.
If you can observe both sides of the fish, you may see that a gill cover is clapped shut or permanently open. Other signs may be skin cloudiness resulting from excess mucus production.
A definite diagnosis can only be made via a skin scrape or gill biopsy. In large numbers, flukes will kill fish either directly, or indirectly through secondary infections. So you should treat afterwards with a general bacteria treatment.
