I ordered 4 of these fans from newegg over the weekend so they should be here this week. Once I get them in I will install them on the lids and take a picture.

If your making a SM100 clone, that should be really easy to swap out the T5s with LEDs. You can either go with a real heatsink to fit from www.heatsinkusa.com or just a couple pieces of Channel Aluminum, either way it would be very easy to mount a couple 80mm fans on the backside to keep the LEDs cool.

Few things factored into my screen size... but mostly a lot of guessing and crossing my fingers it worked. Before I ran 2 10" screens on my ATS, so I knew it could handle 20" worth before, but this time I T'd in my BRS Dual Reactor and chiller directly to my return line, lowering the overall flow from my overflow... so as a guess I thought 12" would be about right. Another factor was I designed my sump/baffles to lengths I just pulled out of my behind.. 18" for the first chamber, and it just so happened that with the PVC parts all attached, I got exactly a 12" slot.. actually about 11-3/4, I had to cut a couple squares off a top corner to get the screen to fit good.

I am feeding about 4 cubes worth of food a day.. I was up to about 8 cubes at my peak of my first ATS and it was handling it great... then I made a really stupid mistake and tried out bio-pellets, while running an ATS, and let me tell you from first hand experience, absolutely horrible idea and it crashed my tank a second time in a year. I thought before hand it may cause the algae to die off... but never expected it to do it so fast and to make such a nasty mess of my tank and sump.
