no cover on tank

not sure if this is the right place but here we go anyway. i am about to plant a 75 gallon tank. im going to be getting a 4 foot 4 bulb tek light to hang over the top. i was wondering what you guys do when you hang the light over the top. do you use a glass top? do you just leave it open? if you leave it open how fast does the water evaporate from the tank? is there anything else i should know about hanging a light above an open tank?

thanks for the help.

After one of my fish burnt itself by jumping on the CFL light, i have placed an acrylic sheet over the tank. The reason i dint use glass was because i keep moving the acrylic sheet during feeding and regular maintainance and it does not break when i accidentally drop it. I'm quite clumsy

I use plastic mesh. No need to move anything for feedings, ferts, I even cut a 2" hole so I can fit my DIY water changer in. I think I lose a 3-4 gallons a week to evaporation.

Glass reflects about 4% of visible light from each surface at normal incidence. Since your glass cover has two sides (top and bottom), about 8% of your light will be lost. More will be lost, of course, if you glass is dirty or tinted.

That's why I decided to go with the mesh. My glass tops were constantly dirty and it gets hard to get some of the gunk off as time goes on.

I leave the cover off of my 55g tall tank. I have a coralife 2x65w fixture sitting on top of the tank. Luckily I have never had a jumper. And I estimate that I lose 3-4gal of water per week.
