part one. i live in australia and cannot get prazzi pro here only tablets.each tablet contains 100mg of praziquantel. recommended dose 2 tablets per 40 liters, this is like your 10 gallon breeder.
this works out to be 5mg per liter. on a us site with prazzi pro it says the does should be no more than 2.5 mg per liter.
can anyone check this on a bottle you have please

part two this is the reason i ask if i have overdosed. On a 40 ltr tank i have one air stone running and a small power head no filter, breaking the surface. i brought home a foxface let it stay for 48 hrs in tank all ok eating everything seemed ok i dosed with 2 tablets as per my instructions 24 hrs later fish is dead. there are no marks at all no white spots the fish just very slowly started to stop swimming breathing heavy then died. ok i thought stress.

i have a second 40ltr tank i brought home two wrasse orange back and blue. i decided to use trank transfer method because i had read they dont like copper much.
first 72 hrs fine both eating and swimming around tank. done a tank trasnfer left for 24 hrs all eating swimming fine dosed 2 tablets 24 hrs both fish dead. i have used magnifing glass ect no stpots nothing, the first fish just slowly stopped swimming heaving breathing then died second fish followed within 1 hour.
all tanks running air stone on high all tanks using power head breaking service. no stops rash dust eyes clear no slime no white poo
any help please i am trying to work out what i am doing wrong.

You over dosed. Directions says it’s 5ml per 20 gallons.

Sorry to hear about your fish, since your country has apparently banned the semi automatic assault bottle of prazi pro, perhaps one of the experts can offer you some advice on your dosage @Frtdrmrose7

Sorry for your losses, hope we can help you out for future issues.

Unfortunately it appears like your dosed almost 80 times the recommended amount. I am willing to bet that is what took the fish.

EDIT-I am so sorry, I misread your units of measurement, let me recalculate.

Double Edit-I have done this math several times and it isn't making sense. When I convert ml to mg it appears you are very much below the dose.

Ok one packet of General Cure has 250mg of metro and 75mg of Prazi. Which is dosed at 75mg per 10G or 38L.
The liquid Prazipro is dosed at one teaspoon per 20G or 76L and that works out to 2.5mg/L.

thankyou all the the help. i will get another foxface on my next trip, my local fish shop is 300km away. i will just use the tank transfer method and not use my blue planet prazzi tablets and see what happens. the first four fish i added to the tank went thru copper treatment. i have hanna copper checker, i did not use the prazzi, and all was ok. i will see if i can get some different prazzzi from the states.
the blue planet tablets that i use says "each tablet contains 100mg of praziquantle". use 1 tablet per 20 liters.
again many thanks
