Active Aqua Reservoir Cover, Black, 50 gal

Convex, Ribbed Cover Design for Stronger Reservoirs

This 50 gallon black reservoir cover is slightly convex with a ribbed design for strength, so it fits inside the reservoir top and channels any collected water back into the tank.

It includes a porthole for routine maintenance access (porthole cover available separately) along with multiple drill points for installing meters and pump cords.

Who Should Use a 50 Gallon Black Active Aqua Reservoir

Growers running a 50 gallon Active Aqua reservoir who want a cover that resists sagging and keeps any surface water draining back into the tank will find this black cover useful.

Why a Convex, Ribbed Cover Matters

A flat cover can allow water to pool on top and eventually leak around the edges; the slightly convex, ribbed shape sheds that water back into the reservoir instead.
