Innovative Marine Aquarium Lids & Covers

A DIY (do it yourself) lid is difficult to assemble, is flimsy / weak in construction, does not fit precisely around most equipment (leaves large gaps), and makes the top of your tank look cheap. Glass lids are heavy and difficult to move, collect condensation and salt creep that blocks light and constantly needs to be cleaned, and can easily shatter if accidentally dropped or stepped on. Acrylic lids bow up at the corners and cloud / haze over the course of weeks or months, leaving an ugly and unprofessional look as well as large gaps for fish to jump through. Custom polycarbonate screened aquarium covers are designed according to the exact measurements we've used to create hundreds of other lids for the same tank model. It will not only fit perfectly with no gaps, but will also have close to 0 condensation due to being screened, have all cutouts like Feed Doors, Light Cutouts, and Auto Feeder Cutouts precisely fit to your exact specifications that you configure on the Product Page, be warrantied for 3-5 years against bowing, clouding, and hazing, and keep a clean and professional look to add to the aesthetics of your aquarium.

Our custom polycarbonate aquarium lids come with a clear polycarbonate frame that has screen inside all openings of the frame to keep fish in and condensation low. To reduce evaporation, choose our Evaporation Cover option which is a solid piece of polycarbonate material that covers the screened portion of the lid to stop ~60-70% of water evaporation from your aquarium. This greatly helps reduce the need for frequent top offs and maintains stable water conditions.
