I would like to make a large scale ocean ( guided ocean layer extended) But I can't put two wavetanks into the simulation. Can you help me? Thank you

I tried to put to two wavetanks into a giant simulation but the color of the water in the first tank was much dark darker than the other. I tried with different oceansurface materials and tried with the same but nothing. What is the proper way to add to flat tanks into one simulation?

Thank you again.
