If its the NutraFin one then no.
One thing with the NUtraFin is that the mix that you get isnt that great, its basically what i sugested but for about triple the price, and the mix i sugested to you gives more Co2 for the mix and lasts longer.
it's just a 2litre bottle with the pipe sealed into a hole in the cap + your suggested mixture.
