Keep the fish in, without preventing air flow! These mesh lids were designed to hang inside of rimless tanks, but they can sit inside of tanks with rims. They are 3/8″ thick and the mesh screen is 1/4″. At JT Custom Acrylics all builds are custom, if you have a uniquely shaped tank we can make a cover. The breakdown is, on average, $23 a square foot.
I am able to add things like:
– Auto feeder down tubes (keeps the food in the tube until it sinks)
– Electrical wires
– Hang on back equipment
– Small access lids/flaps
Here is the frame I made for my mesh lid. This is about 36″ square. The larger notch is for power cords and the return line. The small opening is for my overflow box. I will be making a black insert for it, it will keep the light out of the overflow.
