Custom Red Sea Polycarbonate Lid

Polycarbonate is the best material for reef lids because it offers the perfect balance of strength, clarity, and durability in a saltwater environment. Unlike acrylic, polycarbonate doesn’t bow, crack, or break under heat, humidity, or lighting. It stays structurally solid even under high-intensity LEDs, which is essential for coral growth.

Acrylic lids often warp over time, but polycarbonate holds its shape. It’s designed to handle constant moisture, evaporation, and temperature changes without distorting. That means your lid continues to fit flush and tight—keeping humidity in and your system clean.

Polycarbonate also has excellent light transmission, so you keep the look of an open-top tank without sacrificing PAR. Your lighting performs the way you intended, and your viewing experience stays crystal clear.
