We could definately look into getting Sodium Thiosulfate in bulk. I think the 50lb drum may be a bit much to store unless someone has more room than I do. I do imagine Greg buys the 50lb drums of it but I'm not sure.
Before going the 50lb route, we should check and see if anyone at GCAS already orders this in bulk. If not, we could easily sell some if it to the GCAS members also! It could be a decent fund-raiser if the shipping is not prohibitive. If you are still procrastinating, feel free to check into the shipping costs on drum and the 4 pounders for us
I don't have any idea how to even mix the stuff up though I'm sure there is plenty of info out there...
