EcoPlus® Air Stone - Small - Round

EcoPlus® Air Stone - Small - Round

The EcoPlus® Small Round Air Stone adds oxygen and promotes nutrient circulation in hydroponic reservoirs and grow systems. Delivering 3-5 liters per minute of fine bubble aeration, it helps maintain even water temperature, keeps nutrients in suspension, and supports the root zone oxygen levels that drive healthy plant growth. Recommended for 5-15 gallon reservoirs. Use with 3/16in ID airline tubing (product #708215).

Key Features & Benefits

• Fine Bubble Aeration — 3-5 LPM of dissolved oxygen delivered directly into the reservoir.
• Nutrient Circulation — keeps nutrients in suspension to prevent stratification.
• Temperature Stabilization — continuous water movement helps maintain even reservoir temperature.
• Recommended Tank Size: 5-15 Gallons — right-sized for effective oxygenation.
• Compatible with 3/16in ID Airline Tubing — connects directly to standard airline lines from any air pump.

Who Should Use This

Hydroponic growers running DWC, recirculating, or reservoir-based systems who want to maintain optimal dissolved oxygen levels and nutrient circulation in their root zone.

Compatibility

Use with 3/16in ID airline tubing (product #708215). Recommended for 5-15 gallon reservoirs. Connect to any standard air pump.

Frequently Asked Questions

What airline tubing size does this use?

Standard 3/16in ID airline tubing (EcoPlus product #708215 or equivalent).

How does aeration benefit my reservoir?

Dissolved oxygen in the root zone accelerates nutrient uptake, supports beneficial microbial populations, and prevents the anaerobic conditions that lead to root rot.

How many air stones do I need?

A general guideline is one appropriately sized air stone per 5-20 gallons depending on plant load. Larger, denser systems benefit from multiple stones.

Can I use this with any air pump?

Yes — any air pump with a standard 3/16in output fitting and sufficient flow to meet the 3-5 LPM rating will work with this air stone.
