I'm going to prepare some ID11 (1L) for developing some sheets of HP5+ tomorrow.
As I've got more than six sheets (the MOD54 in the 1L Paterson tank only holds six sheets) to develop, I'm thinking of making a 1+1 dilution so I can load up the tank twice.
Is this the way to make a 1+1 solution?
Pour the Part A powder in about 600ml of deionised water. Use stirrer to mix.
Add Part B powder and top up with deionised water to make 1 litre of stock solution.
Pour off 500ml of the stock solution into a separate container. Top up each of the two containers with 500ml of deionised water to make a total of 2L of 1+1.
Or do I just use the stock solution twice, and increase the development time the second time?
