In the past, I've always bought the packet of Kodak HCA that made about 1L of stock solution, which makes 1.25 gallons of working solution, I think. B&H now no longer offers this size and I read that Kodak stopped making it and now only sells the packet that makes 1 gallon of stock solution (5 gallons working solution!). The last time I ordered, I got the 1 gallon pack without even realizing it. I guess I didn't notice that the small packet had been discontinued and just ordered the large one, thinking that it was the small one. Well, there is no way that I can use 1 gallon of HCA stock solution in 3 months, which is about how long it lasts after it's mixed, according to Kodak. I know that it's not recommended that people separate developers like D-76 into smaller amounts for mixing, as the various ingredients are probably not uniformly dispersed in the powder, but is the same thing true or as critical when dealing with Kodak HCA? I've looked into other wash aids on B&H's website, but the pricing on those is just ridiculous. To me, the 1L Kodak HCA stock solution packet was the perfect size and I was able to easily use it in 3 months when developing film. Oh, and I'm using Kodak's powdered Fixer, which has a hardener, so that's why I need HCA. So, can I somehow weigh out about a quart's worth of the HCA powder and put the other 3/4into separate packages for later use? Has anyone here done that, or is it also not recommended?
