Please read this and digest it carefully!!! Ok here’s the deal with Praziquantel or more specifically 100% pure prazi. Praziquantel for koi carp originated in the United States where Tom Holder some years ago marketed Prazipond for Koi which was and is 100% pure prazi and still is today. it was originally and still is an equine wormer. Then several years later came fluksolve which is 50% pure prazi which as you can see is half the strength Dose rates: In the States 100% pure prazi is dosed at 10gm per 1000 US gallons or 10 gm per 800 UK gallons as a US gallon is 20% less than ours this is a very strong dose compared to our approach Flukesolve is dosed at 10gm for 550 gallons but its only 50% as strong so flukesolve would equate to 10 gm pure to 1100 gallons Doc Johnson of Koivet advocates 7gm of 100%prazi to 1000 US gallons which equates to 3.5 grams to 400 uk gallons, which if you downscale it to our 50% prazi as used in flukesolve is the same dose rate as flukesolve at 10 gm per 550 UK gallons, so doc Johnsons view is more in line with the Uk’s flukesolve does rate. So it’s a bit confusing but it’s not really if you look at it logically we are dealing with two concentration of the same compound 100% and 50% Its universally accepted that Prazi is an absolute swine to dissolve ! And guess what it dissolves readily into? Yes preform c without any loss of product. PROFORM C is a premix of malachite green and formaldehyde So if we come back to the dissolving problem, even flukesolve does not dissolve readily but I believe it’s better than pure prazi. Because a lot of it ends up in suspension rather than being dissolved, there’s a difference between dissolving something and putting it into suspension. In America if you want to dissolve it WITHOUT Proform c, you put the dose into a plastic litre pop bottle fill it with plain water and shake the whey out of it for 3 minutes and at least 70% of the stuff will dissolve ( this is in the prazipond instruction) then you add this to a bucket of pond water and most of the rest dissolves you then add to the pond and over a day or two you get a total dissolve. With this in mind, I got to thinking about the proform C /Prazi combination and started to think I wonder if???? As Proform c is malachite green and formaldehyde, my thinking was, the malachite aspect of the combo was/is insignificant in the dissolving process as it’s just a salt, so it had to be the formaldehyde , so I set about seeing how little you could get away with and came up with this formula 5 grams of Prazi + 5 ml of formaldehyde plus 5 ml of water mix this with vigour for a couple of minutes and you get a white free flowing paste and almost total dissolved prazi, let it stand for a 5 minutes then top up with tap water stirring as you add water and you will find you have totally dissolved the powder 100% add this to a buck of pond water and mix then spread around the pond wolla! The impact of this is it does not affect the prazi as formaldehyde is amongst other things a preservative and it will have no effect on your filter and fish as it’s a very low amount of low concentration.. Conclusions are this: My 100% pure Prazi I’m happy to recommend a dose rate of 10 gram to 1000-1100 gallons or you can if you wish go down to 10 gm per 850 gallons. Its filter and plant safe and no water change is needed and it’s a one shot treatment, its sturgeon , orfe and rudd safe You can if you wish dissolve this as out lined by putting the dose in a pop bottle and shake the crap out of it then adding to a bucket of pond water and spreading around the pond. Or you can if you wish dissolve it readily by using 5ml of formaldhyde to this add 5 ml/cc of plain water to 5 gram of Prazi and makes a free flowing paste then let it stand for a few minutes and stir as you top up with water then add to a bucket of pond water, so the formaldehyde approach is 5, 5 and 5, the formula is scaled up or down for different amounts, for instance if it was 15 gm you were putting in it would be 15gm prazi + 15ml formalin + 15 ml of water, if it was 30 gm it would be 30 gm of prazi plus 30 ml of formalin + 30 ml of water, get the picture? its the most you need to 100% dissolve the prazi without impacting fish or pond i suspect as is the case with flubenol and acetone as you start dealing with higher weights you would get away with less liquid. Now I have the stuff here and the price is going to be circa £1 per gram plus a bit of delivery, I will be doing it in 10gm packs to treat 1000 gallons and 25 gm to treat 2750 uk gallons slightly less so the price for 10 gm is £13 including first class delivery and the price for 25 gram is £23 including first class delivery special offer for this month 30 gm for the price of 25 gm this would treat 3300 gallons chemicalfactory.co.uk Your comments as usual are welcome Duncan
