The tank is looking great so far. Can't wait to see it when you get some rockwork established. How many overflows are you going to have? 1100gph return pump seems like a lot. You will need to ensure that your overflow(s) can handle that much flow. Most people will agree that you really don't need tons of flow going through the sump/fuge. The flow through my fuge is pretty light at around 550 gph, but I have a tunze 6060, a Seio 1100, a maxijet, and a rio 600 in my tank for increased flow and I have a 75 gallon. Personally I would use a smaller return pump and slow down the flow through the fuge and use a closed loop or efficient powerheads (like tunze streams or seios) for extra flow in the tank. 1100 gph on the retun pump will overpower a 1" pvc return line easily. Is there any reason that you plan on running 46.5" Vho's instead of T5HO's? VHO's last around 6 months whereas T5's will last around 1 year or longer and the bulbs are roughly the same price. T5's also use half the electricity as VHO's (54 watts compared to 110 watts) and produce far less heat. Plus you can fit more T5's over your tank than you can VHO's. Before making the plunge into a VHO setup I would suggest that you do some research on T5's and get some opinions from other people that are using them. Personally I think that you will be much happier and get better results from the T5's.
Anyways, Thanks for sharing your photos and please keep us updated on your progress. It is always great to see progression photos that start from the initial setup.
