Active Aqua 75 Gal Black Reservoir Lid | 43.5in x 43.5in, UV ABS

Why the 75 Gal Reservoir Lid Sits Inside the Rim

The measurement surprises people. The lid is 43.5 in x 43.5 in while the tank it fits is wider than that. This cover drops down inside the reservoir top rather than capping it. Condensation, spray and anything you spill while topping off runs back into solution instead of down the outside of the tank. The top is slightly convex and ribbed, doing two jobs at once. The ribs stiffen a large flat panel that would otherwise oil-can, and the curve sends standing water to the edge.

Cutting a Hydroponic Reservoir Cover for Probes and Cords

Multi-drill access points are moulded in, so meters, probe leads and pump cords go through at marked spots rather than wherever the hole saw lands. Plan the layout before cutting, since a lid full of unused holes stops being a light barrier. That barrier is most of the value here. A covered tank in a lit room keeps algae out of the solution. Algae is what turns a clean reservoir into a biofilm problem inside a couple of weeks. Body is high-impact UV-resistant ABS with thicker walls and stronger corners than most covers in its class. One thing to know first. The access port hole cover is a separate item, so a lid on its own gives you drill points but not a hinged port.

Key Features

• Fits inside the reservoir top: Water landing on the lid falls back into the tank rather than running down the outside.
• Convex and ribbed top: Ribs stiffen a large flat panel and the curve moves standing water to the edge.
• Multi-drill access points: Marked positions for meters, probe leads and pump cords instead of guessing with a hole saw.
• Blocks light on the solution: Keeps a lit room from turning a clean reservoir into an algae and biofilm problem.
• High-impact UV-resistant ABS: Thicker walls and stronger corners than most covers in its class, and it does not chalk under light.
