Active Aqua Reservoir Cover, Black, 50 gal

Convex, Ribbed Cover Design for Stronger Reservoirs, 50 gal

A flat reservoir cover can let water pool on top and eventually leak around the edges, especially once it's carrying the weight of cords, meters, or splash from an active system. This 50 gal 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 instead of letting it pool.

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

Frequently Asked Questions

What size reservoir does this cover fit?

This cover is sized to fit a 50 gal Active Aqua reservoir. Using a cover matched to your reservoir's exact size keeps the ribbed edge seated correctly.

Does this cover include a porthole?

Yes, though the porthole cover itself is sold separately. The porthole gives quick access for routine tasks like checking pH or adding nutrients without removing the whole cover.

How do I install meters or pump cords through this cover?

Use the pre-marked drill points to create openings sized for your specific meter probes or pump cords, rather than drilling into an unmarked section of the cover. This keeps the openings positioned where they won't compromise the cover's ribbed strength.

Can I install meters or pump cords through this cover?

Yes, it has multiple drill points for that purpose, positioned so growers can add meter probes or pump cords without weakening the cover's structure. This makes it practical to outfit a reservoir with monitoring equipment after the fact.

Why is the cover convex instead of flat?

The slightly convex shape sheds any water that collects on top back into the reservoir instead of letting it pool and eventually leak around the edges. Combined with the ribbed design, it also resists sagging under the weight of cords or splash.
