Probably just stating the obvious here, but if you are mixing your own developers and hypo eliminator you go through lots of Sodium Sulfite and Sodium Carbonate. I have found that going to a chemical supply house and buying those chemicals in 50 lb bags lowers the cost by about 75%. Less than $50.00 each... a dollar a pound. you can keep it fresh at that rate.
