Red Sea Reefer 250 G1, G2+, and G3 Custom Polycarbonate Aquarium Screen Top Lid

Our lid frames are made from polycarbonate, thick enough to thoroughly support the lid, but slim enough to keep away excessive condensation and salt creep. Our screens are individually made for us, with thin screen fibers that let through more PAR than other screens, and openings small enough (slightly larger than 1/8") for even the smallest fish or eels to not wiggle through. These materials are water-resistant, easy to clean, and provide long-lasting multi-year protection for your aquarium.
