The return system ended up being too close to the tanks to open the lids... I was worried about how I was going to get the water down into the tanks and wasn't thinking about opening the tanks. Well, that's been fixed now by inserting a small section of pipe into the vertical return.
We've got 5 of the 6 tanks on the bottom row running with critters (the 6th is leaking). Now I have to figure out how to fix this (the upper return drops about 3 inches going to the other side and space is tight over there):
I tracked down a piece of twinwall polycarbonate and made some lids. My first time working with this material. I had expected it to be more forgiving... its basically like working with plywood... clear plywood. I found it pretty difficult to cut in a straight line due to the clarity. It's tough to keep track of where the line is, it messes with your depth perception. Using a medium speed with the jigsaw and pulsing/cutting in short sections seemed to be the most effective method. I then used sand paper for dialing in the fit.
I might use this in a few other places in the fish room to tighten up our evaporation and control humidity.
