Active Aqua Reservoir Lids

This lid is specifically engineered to fit Active Aqua 75-gallon reservoirs. While it might physically sit on other brands, the secure fit and drainage alignment are optimized for the Active Aqua system, so we recommend using it with the matching reservoir to ensure a proper seal.

The lid features pre-marked, reinforced areas specifically designed for drilling. This allows you to customize the placement of your pump cords, air lines, and sensors without compromising the structural integrity of the lid.

Yes, the convex, ribbed design is built for structural strength. It is designed to handle the weight of standard hydroponic setups, though you should always distribute weight evenly to avoid localized stress on the plastic.

The convex, ribbed shape serves two purposes: it adds significant rigidity to the plastic to prevent sagging, and it ensures that any water or nutrient runoff drains back into the reservoir rather than pooling on top, which helps keep your grow area clean.

Yes, the high-impact ABS plastic is treated to resist UV degradation. It is designed to withstand the harsh environment of a greenhouse without becoming brittle or warping over time.
