I havn't got the final design from him yet.  There is going ot be an overflow box from the tank down into the sump adnthen into the skimmer, so I would imagine right from the tank.  I could get some stuff changed too, he is just in the process of engeneering my sump now.  I will ask him about the bigger sedra model.  Shouldn't be too much of a jump in price you would think.
