Grey tank to black tank crossover

Our 2 black tanks hold twice the size of our 1 grey for some unknown reason. 78>38. Yes those are the numbers. Has anyone made some type of connection so the grey starts to get full, the flow will fill to the black? Pics and or step by step would be great. This is a must should we do dry camping.
