Ok so i need to make a tank lid for my 75 gallon tank it has two 16x22 openings and i can't find anything premade. I need to make something that holds in humidity because i have two 150 watt bulbs on a thermostat. My humidity is always at least 50 but any ways i need ideas of what to make it with and how. i am a fairly decent carpenter and have access to a LOT of tools. So i need ideas thanks guys -Josh
