Right now my 40B doesn't have a lid, and I do have anxiety waking up every morning making sure all the fish are there. In the past I used the versa top lids but there were many things about them I didn't like. Based on the current configuration of my LED clamps, filter, cords, etc. I would need a custom solution. I looked at some vendors who make custom lids and the price was $250+ due to all the cutouts needed (not to mention the long production time). I'm hoping I can create a more economically feasible lid on my own. I've included a pic and diagram of the tank and would welcome any ideas or resources!
