PraziPond Plus Praziquantel (“Prazi”) is the preeminent treatment for flukes. ‘Prazi’ is by far the most gentle, yet effective treatment for flukes available to our hobby. The real bonus with ‘Prazi’ is that when you treat for flukes it also rids the fish of any internal parasites or worms.
‘Prazi’ is extremely effective for the treatment of external flukes, liver flukes, internal parasites and internal worms in koi, goldfish and tropical fish. ‘Prazi’ is a one time treatment and because it is so gentle, it does NOT require any water changes after treatment and you do NOT need to bypass your biofilter. Prazi also will work with any amount of salt in the pond and it is not water temperature dependant.
PraziPond Plus is USP grade (99.5% pure) prazi blended with cyanocobalamin and a proprietary polymer mixture. No other prazi available today has this advanced formula. PraziPond Plus is 40% more effective than prazi alone.
As a preventative, we recommend treating once a year in early Spring.
Available in 10 and 50 gram bottles:
APPLYING PRAZIPOND PLUS TO YOUR POND
Caution: The only accurate way to measure Prazi Pond Plus for dosing is by weight. Measuring Prazi Pond Plus, assuming a tablespoon is equivalent to 2.9 grams is not accurate. Due to settling of the product in shipping and when scooping it out ofthe jar, 1tablespoon could contain as much as 7 or 8 grams of Prazi Pond Plus.
Only one treatment is needed and no water changes are required after the 7 day treatment period. During the 7 day treatment do not do any water changes. Water can be added to the pond during the treatment period as needed due to evaporation, etc. Turn off uv lights for alleasl 4 days al start of trealment period.
Dissolving Prazi in water: Prazi does nol dissolve easily in water. There are various methods for applying Prazi to your pond. First of all please note that you do NOT need to achieve a 100% dissolving rate when mixing Prazi with water. Prazi will totally dissolve in your pond over a short period of time after application. When applying Prazi to your pond while it is only partially dissolved is not dangerous to your fish even if they eat the Prazi flakes in the water.
Prazi is NOT harmful to your biofilter. Prazi treatments are effective at ANY water temperature.
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.
