Once the water is in. The next step is to add fresh Developer Starter. Again, follow the recipe. Ours calls for 3900 mls. Make sure to measure carefully.

The final part of the recipe calls for replenisher (a premix of developer and water). The easiest way to get it is to use a clean siphon to get the amount you need from the replenishment tank.

Add the premix to the tank and you are all done. This is what a clean developer tank should look like. Put the racks back in and make sure to run control strips to make sure everything is calibrated.
