Well, I'm not Stephen, but my question is: what are you trying to DO?  All
you have is a drawing of a tank plumbing system, not any descriptive text. 
Why a chiller? Why inline CO2 reactor?  Why use a canister filter as a
return from a sump?

Generally folks do not route their entire water return through the CO2
reactor, just fork off a small flow which then returns to the sump.

Generally folks use strong powerheads or strong pumps to return the water
to the tank from the sump, because canister filters are not designed for
that much head.  If you want to use the canister filter, you should
probably have it just return to the sump and use a better pump as the tank

I have bought 4-tube electronic ballasts for $25, but they are for
instant-start T-8's, not NO, HO or VHO types.  I can say that a four-tube
T-8 system over a 55 looks quite snazzy, and can be built for about $50-60
(including ballast, 5000K bulbs, wires and hardware).  These ballasts are
quite definitely parallel, because the 4-tube model is also used as the
3-tube model by leaving one lead unconnected.
