Jobo 1500 Tank System

[Gary Spicer]

I have a 1520 Jobo tank which takes 240 ml of chemical for rotation development. I have added a 1530 extension tank and that says 330ml of chemical. My question is this, when the tanks are combined do I add 330ml or 570ml of chemical. Just need to be sure, I would assume 570ml? thanks Gary

Those are minimum quantities, you would be safer rounding up to 600ml.

Thanks Guys. I am buying 1 litre E6/C41 kits and wanted to get good economy from them so was looking at 2 x 500ml mixes but clearly this wont work. So have bought a 1510 tank as this combined with the 1530 only needs 470ml so can round up to 500ml!
