A mesh top will allow evaporative cooling to occur. Blowing a fan across the top of your tank will generally yield a couple degree difference in water temperature. Mesh tops are preferred over no top to keep fish from jumping out. The mesh also allows nearly 100% light to penetrate the tank, and doesn't build up condensation/salt creep like a traditional glass top. For more info, here is the original diy thread: Clear mesh top - Reef 2 Reef
I have both 1/4 and 1/2 inch mesh size available. If you have small fish, you should use the 1/4 inch. Neither one has a visibile effect on the light in the tank. 1/2 inch is a thicker material.
Here is a price schedule for just the mesh for this easy DIY project for the some common tank sizes, including shipping:
12x24 = $15
12x36 = $18
12x48 = $20
24x48 = $25
20x20 = $20
20x46 = $30
36x48 = $35
I still have most of a roll of this stuff left and I can cut to accommodate whatever size you need.
