Hi I'm currently running a railcraft tank that stores lava from one liquid tesseract from the nether,  i have then got 3 valves which has liquiducts leading to 9 geo thermal generators,  however,  the amountof lava that is put in the tank is not as much as the lava that is being taken out.  So I was wondering what i should do to increase more lava intake to the tank?  Sbould i get another tesseract or more pipes that lead from that single tesseract?
