777 has a reputation for lasting a long time and being suitable for replenishment. It might work best if you mix the entire batch, depending on how much you have.

 

Dividing the powder to make less than a full gallon might result in an inaccurate mixture. One manufacturer of commercially prepared 777 recommends mixing a full gallon, which is then divided into two half-gallons. Use the second half-gallon to replenish the first.

Never break up a kit. First it is not guaranteed uniform and second the remaining balance

can not be made oxygen free under home conditions so it stands a good chance of spoiling.

It's ok to break up a 4 gallon kit and use it in 1 gallon batches, but as a previous poster pointed out, exposure to air will ruin 777 quickly. Even though I keep mine tightly capped in full bottles, I change my working gallon of 777 once every six months. I mix up a fresh gallon, replace half of my working gallon and use the rest as replenisher.

 

777 was designed to be heavily used in 4 gallon deep tanks. You need a lot of solution to use it well. I never develop more than two 8x10 sheets (or rollfilm equivalent) per gallon of solution.

 

Hope this helps.

If you want to make your own, Ed Buffaloe (unblinkingeye.com)figured out the formula, give him try. Besides, my long time Ed has a great site for all in photography to check out.
