F76+ replenishment for 4x5?

Hey apug,
I bought a old but looks brand new, Kodak film pack tank #2. it calls for the use of 53 oz of developer/stopbath/fix etc. I was planning to mix a gallon of f76+ to order to develop. The tank processes 12 sheets folded vertical taco style. My question is since I plan on reusing the developer, how do I replenish the developer? I don't think that Clayton/arista sells a replenisher for it. Is there a formula to make a developer into a replenisher, for example using a stronger dilution of the original developer. I was planning to mix the gallon at 1:9.
Also isn't that a formula to know how much replenisher to add to the bottle based on number of sheets proccessed?

Thanks,
Scott Hunnicutt

Scott, you'd be better making up both the developer and replenisher from raw chemicals.

The D76 formula was here in the chemistry section but seems to have disappeared,

D76 (ID-11).

Metol 2g
Sodium Sulphite, anhyd 100g
Hydroquinone 5g
Borax 2g
Water to 1 litre



D76 (ID-11) Replenisher

Metol 3g
Sodium Sulphite, anhyd 100g
Hydroquinone 7.5g
Borax 20g
Water to 1 litre


The replenishment rates are given in the Kodak data sheet
