First pic is my DIY screen top with the clear mesh I bought from BulkReefSupply, rest was bought at lowes. Cost me about 30 bucks for all the materials, give or take, but worth it. I now have a pair of flasher wrasse's that I wouldn't have otherwise. No pics of them, my camera is too slow to get a good pic.
I just re-arranged my tank and now have a much more open area in the middle. I plan to get another clam or two (maxima ultra) to take up some of the sandbed in the front. I can't believe I didn't do this a long time ago!
