THROUGH THE Cultivator's LENS Hands-On Evaluation

Who This Is For

  • You are upgrading your irrigation setup because your current reservoir walls are bowing and leaking under full volume
  • You are building out a large-scale recirculating system because you need a specific square footprint to maximize room efficiency

What We Found

  • The 3-layer construction feels much more rigid than standard reservoirs, which prevents the sides from flexing when filled
  • The dark pigment is opaque enough that you can stop worrying about light leaks and extra covers for the tank body

What Users Say

  • Users who swapped out their old single-wall tanks report no more algae buildup inside the reservoir
  • Operators who switched to this square design say they saved valuable floor space in their irrigation room

Active Aqua 2.0 Black Reservoir - 100 Gallon

Most reservoirs on the market make compromises — thin walls that flex under full load, materials that degrade under UV exposure, or designs that cut costs at the expense of long-term durability. The Active Aqua 2.0 Reservoir is built to a different standard, using a proprietary 3-layer high impact polystyrene blend that is food-safe, UV-stable, and heat resistant. At 100 gallons and a square 51" × 51" footprint, it suits large-scale recirculating systems and centralized configurations. To maintain high oxygen levels in the solution, many growers integrate an Active Aqua Round Air Stone for consistent nutrient aeration.

The 2.0 designation reflects an updated construction over previous generations — the 3-layer wall composition delivers meaningfully better rigidity and impact resistance than single-wall alternatives at comparable price points. The black exterior blocks light penetration to the nutrient solution, inhibiting algae growth without requiring additional covers or wrapping on the reservoir body itself. Note that this listing is for the reservoir only — no lid is included.

Features

🧱
3-Layer Polystyrene Construction

A proprietary 3-layer high impact polystyrene blend delivers superior rigidity, impact resistance, and wall strength compared to standard single-wall reservoir designs.

✅
Food-Safe Material

Made from food-safe polystyrene — safe for direct contact with hydroponic nutrient solutions and edible crop irrigation without leaching harmful compounds.

☀️
UV-Stable & Heat Resistant

UV-stable construction resists degradation from light exposure, while heat resistance ensures structural integrity holds up under warm grow room conditions over time.

🟫
Light-Blocking Black Exterior

The opaque black body blocks light from reaching the nutrient solution, inhibiting algae growth. Using Active Aqua Black Vinyl Tubing for your plumbing further ensures the entire system remains light-proof.

📐
Square 100-Gallon Design

The 51" × 51" square footprint maximizes floor space efficiency, especially when paired with an Active Aqua 4 x 8 Rolling Bench System for high-capacity professional grow room management.

♻️
Recyclable & Made in North America

Manufactured in North America from recyclable polystyrene — a more sustainable choice for growers who prioritize responsible sourcing alongside performance.

Frequently Asked Questions

Does this reservoir come with a lid? +

No — this listing is for the reservoir only. A compatible Active Aqua Premium White Reservoir Cover is available separately and is recommended to block light and reduce evaporation. The Active Aqua Black Porthole Cover for the reservoir lid is also sold separately.

What makes the 2.0 reservoir different from earlier Active Aqua reservoir versions? +

The 2.0 series features a proprietary 3-layer high impact polystyrene construction that improves on the wall rigidity, impact resistance, and overall durability of previous single-wall designs. The updated material blend is also UV-stable and heat resistant, making it better suited for the demanding conditions of active grow rooms over extended use.

Is polystyrene safe for hydroponic nutrient solutions? +

Yes — the Active Aqua 2.0 Reservoir is made from food-safe polystyrene that is safe for prolonged contact with hydroponic nutrient solutions and edible crop systems. The material is inert under normal operating conditions and will not leach harmful compounds into your water supply.

What other reservoir sizes are available in the Active Aqua 2.0 lineup? +

The Active Aqua 2.0 Reservoir lineup is available in 30, 50, 70, and 100 gallon capacities, all in the same black square design with 3-layer polystyrene construction. All sizes share the same material specifications — food-safe, UV-stable, heat resistant, and recyclable — scaled to match different grow room configurations and system sizes.

Can I use the Active Aqua Bottom Draw Pump Adapter with this reservoir? +

Yes — the Active Aqua Bottom Draw Pump Adapter is compatible with the AAPW250 and AAPW400 submersible pumps, both of which can be used inside this reservoir. The adapter draws water from as low as 3/16" depth, making it an effective solution for fully draining the 100-gallon reservoir during nutrient changes without tipping or lifting the tank.

How do I clean and maintain a 100-gallon reservoir between nutrient cycles? +

Drain the reservoir fully using a submersible pump — the Active Aqua Bottom Draw Pump Adapter helps clear the last few inches of solution. Rinse the interior with clean water, then wipe down with a diluted hydrogen peroxide or citric acid solution to break down mineral scale, biofilm, and any residual nutrient deposits. Rinse thoroughly before refilling.
