I haven't noticed the net blocking much light at all. it's very thin material. you can find it at any lowes or home depot in the garden/pond area.

Thanks. I built the stand out of 2x4s and 2x6s but I had a woodworking shop skin the stand. to be honest with you, I don't know exactly what they used.
Also, the top of the tank is the reason I went with the 8 bulb ATI and not the 10 bulb. The opening is 18.5 inches, just about the same size as the 8 bulb fixture so no light is blocked by the top.
@ others
Here's a little info on the top I built. I built the top out of bird netting and the stuff used for window screens. I've never worked with the stuff before but it was very easy. First I measured the top of the tank and made a rectangle out of the aluminum screen stuff to fit on top. then I simply installed the net exactly how I would have if it was screen. (there are directions on the bag of stuff). The netting is very thin so i dont think it will block much light. I'll get more pics when I get time but here are two below.

thanks. i did a lot of research on sump design and I'm very happy with the design I chose. I wanted the sump and refugium to be as big as possible so that's why i went with an internal pump. also, I wanted to run everything off of one pump so the tank would be as efficient as possible. But the sump design itself is pretty basic.
the over flows on the tank lead to the dual filter socks on the right side. Then the water goes go through the skimmer area, through a bubble trap, and into the return area. this is where my ATO system is and of course the return pump.
the return pump feeds water through the chiller (in the garage through the wall) and into the tank. but before the chiller, it tee's off and some water goes to the left into the refugium (which overflows back into the return area). and the other two tee's lead to the carbon reactor and phosban reactor (then they go back into the return area as well).
hope this helped guys.
