Active Aqua 2.0 Reservoir 100 Gallon - Black

A 100-Gallon Reservoir Built to Outlast the Grow

A reservoir that warps, stains, or leaks mid-cycle doesn't just waste solution — it puts the whole grow at risk while you scramble for a replacement.

The Active Aqua 2.0 Reservoir holds 100 gallons in a square black tank measuring 51" x 51" x 13.5", molded from a proprietary high impact polystyrene blend designed specifically for hydroponic use.

That material is UV-stable, food-safe, and heat-resistant, so the tank keeps its shape and seal cycle after cycle — exactly what you want from the tank that everything else in your system depends on.

Key Features & Benefits

• 100-gallon capacity — gives your system enough reserve volume for steady circulation, sized into the 51" x 51" x 13.5" square footprint.
• Square black design — fits cleanly into rack and bench layouts and blocks light from reaching the solution inside.
• Proprietary high impact polystyrene blend — is UV-stable, food-safe, and heat-resistant, so the tank holds up to long-term reservoir duty.
• Reservoir-only, no lid — keeps the unit straightforward to integrate with whatever lid, cover, or bench setup you already run.
• 51" x 51" x 13.5" footprint — is sized to fit standard bench and rack layouts without crowding the rest of your equipment.
• Part of the Active Aqua 2.0 Reservoir lineup — so you can scale up or down to a 30, 50, 70, or 100-gallon size as your system grows.

Who Should Use the 100-Gallon 2.0 Reservoir

This reservoir suits hydroponic growers who need a dependable 100-gallon tank sized to 51" x 51" x 13.5" — whether you're building a new system around this capacity or replacing a tank that's started to show its age.

Choosing the Right Reservoir Size

The Active Aqua 2.0 Reservoir line runs from 30 to 100 gallons — 30-gallon (31" x 31" x 12.5"), 50-gallon (39" x 39" x 12.2"), 70-gallon (45" x 45" x 12.25"), and 100-gallon (51" x 51" x 13.5") — all sharing the same square black design and food-safe material. This 100-gallon model measuring 51" x 51" x 13.5" is sized for setups that call for roughly that volume; sizing up or down keeps your reservoir matched to your system's actual demand.
