I've used Aubiose for ages, with corns, kings, milks, hogs and boas and never had any issue. I believe there are a few other members on here too that use it.
i just started using Aubiose for all my corns and i really like it i got mine order in to my local pet shop and it was only 10 pound for a 20kg and it is going to last me months...............i used to use aspen but had an out break of mites so stoped using it
