do you have 734 sea water? I am not sure you will manage to sell all of them!!! The demand of water in the game is not really high enough for you to sell all these water!!! May be you should make it as fuel for plane, that would sell MUCH better, of course that would depend on the price you offer...

I know you dont have glaze table, either buy one and hope you will make more money from the fuel, or make one of your own.
