That is a decent block, although I don't like the 3 hose design as it makes you run a Y fitting to loop the 2 outflow hoses together. A 2 hose design is just as efficient and gets the same results. I use a DangerDen TDX block and highly recommend it. Make sure you have a good pump with good flowrate. The higher the head that the pump can push is more important than the pressure. Reservoirs are quickly being replaced with T-lines because a T-line is easier to set up and less prone to leak, but I still prefer to run a reservoir.
