If you are racking your parts and those on top are turning out good but the ones on the bottom are not you may be experiencing temperature stratification. To resolve this, mix the solution in your tank, heat naturally rises so the top half of your tank is warmer then the bottom. Another cause could be that your rack is not distributing the current uniformly. You may need a new rack or repair the one you are currently using.
