- TWO PACKS 22.75 x 16.75 x 0.16 Inch PC 75/90/110 Gallon Aquarium Lid - This 75 gallon aquarium lid is specially designed for aquariums with a 48" × 18" top opening and a center support brace (commonly found on 75- and 90-gallon tanks, and select 110-gallon models). Featuring a unique push-style sliding design, the lid opens forward instead of lifting upward, making feeding more comfortable to use and preventing accidental contact with aquarium LED lights. The rear 4.33-inch wide silicone strip can be freely adjusted or trimmed with scissors, allowing easy customization for filters, tubing, and power cords. Constructed from thickened, heat-resistant PC material, this 75 gallon aquarium lid works with most LED aquarium lights and resists warping and yellowing over time. Its crystal-clear transparency provides a fully transparent fish viewing experience without blocking light or visual clarity. Whether for daily feeding, maintenance, or long-term use, this push-style 75 gallon aquarium lid offers a cleaner look, safer operation, and a more user-friendly aquarium experience.
