Some pictures of various layouts that I have for different sizes of aquariums. They range from 10 gallon, 20 gallon, 20 gallon long, 29 gallon, 36 gallon bowfront, 72 gallon bowfront. I mostly make them in clear 3/16" thick polycarbonate but I do make a more economical version using 1/4" twin wall polycarbonate. See my shopify, etsy, ebay, amazon, tik tok shop and facebook marketplace to purchase. Shopify is the cheapest price with the cheaper shipping option. https://zenaquariumlids.myshopify.com/ Instagram: https://www.instagram.com/zen_aquarium_lids?utm_source=qr Etsy 4.8 stars.
