Go
The tank looks cool so far. Here are my thoughts:
1. Is the tube in the middle a supply line from the sump? If so, is it going to have something to prevent it from draining water back into the sump if the pump shuts off? 2. Do you think there will be enough flow throughout the tank with all the supply lines running so close to the overflow? You could maybe add 45* PVC elbows to the ends of the pipes on the sides to help circulate the water. That's about all I can think of. If this tank turns out half as cool as your little cubes did, you'll be laughing.  ________ LovelyWendie99 Last edited by Flusher; 04-21-2011 at 03:15 PM.

The bulkhead on the inner wall of the tank is the intake for the closed loop. The sump is supplied via the overflow. Even though I couldn't really draw it on sketchup, the plan is to have 45 degree elbows on the returns so that the flow is directed towards the lower front of the tank. With 700+ gph from each return, the circulation in the tank should be sufficient - for my plans at least.

Chris,
Actually, what you see on the pump is just what I did with regular old sandpaper. I havent gone over it yet, but will probably finish it off with a pollishing wheel on my dremmel. I am kind of glad that the iwaki is now going to be the sump return... it will be in a more prominent spot and will also be easier to clean. - Chad

Update:
I just picked up the tank yesterday and here's a photo:
 I turned out to be 30"x18"x17" (lwh) and the builder did a pretty good job on it. It initially came with euro bracing but that came off right away - I just like the plain top look more. The inside measurements and my predicted water level make this tank about 35gals; with the expected output of my two pumps, I am figuring that I will have 40x's turnover! There is even room to add more flow if needed (not needed) because my bulkheads are 1.5" but my current pumps have only 3/4" fittings  .- Chad

asmodeus,
Thanks! It sounds like overkill but the plan for this tank was actually zoos and rics. My last three tanks have been in the 30-40x's range and I have always been really pleased with higher flow (as long as the velocity is kept down). My only concern right now is that my sump is a lot smaller than I thought it was - (only 16gals total volume and I still need to leave room for drainage when the pumps are off). I am worried that my 730gph return rate is going to wreak havoc with micro bubbles... The tank builder forgot to add the sheet of black acrylic to the back wall, but he is cutting it for me now and I will put it in myself. I figure that it should look better with the overflow not visible. I am also considering using a razor blade to clean up the silicone job in the corners. Finally, I have the overflow eggcrate off and am going to black that out as well. - Chad
