Hydrogen-rich water for aquariums and display systems
Public and research aquariums manage sensitive aquatic environments with strict water-quality requirements. Hydrogen nano-bubble conditioning can be introduced as a controlled input, aligned with mechanism-level understanding of molecular hydrogen.
HERO Irrigation and HERO Bath systems can be integrated into make-up water and recirculation lines, sized for exhibit-scale and facility-scale deployments.
Hydrogen is a dissolved gas, not a treatment: it does not replace filtration, water changes, dissolved-oxygen management or any part of a life-support regime, and dissolved hydrogen dissipates at the surface over time. Sizing follows circulation volume rather than tank footprint.
Nothing here is aquatic-animal-health or veterinary advice, and no claim is made about fish or invertebrate outcomes. Discuss any change to a display or holding system with your own aquatic-life-support specialist.
Which system suits this application
Home and small display tanks suit the 3.75 L/min system; large public display systems and multi-tank life-support loops suit the 20 L/min system.

Nanobubble technology context
Hydrogen Nano-bubble Technology in Irrigation & Water Treatment
Nanobubbles are gas bubbles below roughly 200 nanometres in diameter. Because they are far smaller than the bubbles produced by a conventional aerator or venturi, they do not rise and burst at the surface: they disperse through the water column and stay in suspension for far longer, which is what growers mean by nano-bubble stability, nano-bubble retention and low nano-bubble lift. A nanobubble generator is simply the device that produces that dispersion, usually as inline nano-bubble injection on the pressurised side of a pump.
Most nanobubble equipment in horticulture dissolves oxygen or air, and some water-remediation equipment dissolves ozone. Oxygen and air nanobubbles are used for water oxygenation and root-zone oxygenation — raising dissolved oxygen in irrigation water, hydroponic nutrient solution and aquaculture ponds. Ozone nanobubbles are used for oxidative water remediation and line hygiene. All three are oxidative or neutral gases: they change the oxygen status of the water, and the accepted mechanism is gas transfer, not redox signalling.
Hydrogen nano-bubbles are the advanced modality in the same delivery format. The HERO Irrigation system uses on-site PEM/SPE electrolysis to infuse 99.99%-purity molecular hydrogen as nano-bubbles directly into the irrigation line immediately before the dripper — pump-inline dosing, no chemical inputs, no storage cylinders, and no change to the existing pipework. Molecular hydrogen is a small, neutral, highly diffusive molecule, so nano-bubble dispersion carries it through the emitter and into the root zone rather than releasing it at the surface. Where oxygen nano-bubbles act on the dissolved-oxygen budget, hydrogen acts as a selective reducing species in the water and the root zone — a different mechanism, and the reason hydrogen nano-bubble infusion is treated as the higher-specification option for irrigation, controlled-environment agriculture, turf, nurseries and vineyards. The two are compatible: hydrogen infusion does not displace an existing dissolved-oxygen programme.
Evidence framing, stated plainly. Strongest: the physical chemistry of nano-bubble formation, stability and dispersion, and the measurable hydrogen concentration delivered at the emitter (3,000–5,000 ppb on this system). Moderate: published plant-science work on hydrogen-rich water and root-zone redox behaviour, most of it small-scale or glasshouse-scale. Gaps: long-run, multi-season, crop-specific yield data across soil types and water chemistries is still limited, and site conditions vary. We publish the mechanism and the delivered concentration; we do not publish crop-performance guarantees.
Nanobubble questions
What are nanobubbles in irrigation?
Nanobubbles are gas bubbles smaller than about 200 nanometres suspended in irrigation water. Unlike aeration bubbles they do not rise and burst, so they remain dispersed through the line and pass through drippers and emitters with the water rather than venting at the surface.
How do hydrogen nano-bubbles differ from oxygen nanobubbles?
Oxygen and air nanobubbles raise dissolved oxygen — a gas-transfer effect used for water oxygenation and root-zone oxygenation. Hydrogen nano-bubbles deliver molecular hydrogen, a small neutral molecule that behaves as a selective reducing species in water. The delivery format is the same; the chemistry is not. Hydrogen infusion is complementary to, not a replacement for, a dissolved-oxygen programme.
What is the difference between micro-bubbles and nano-bubbles?
Micro-bubbles are measured in micrometres and still have enough buoyancy to rise and coalesce within minutes. Nano-bubbles are two to three orders of magnitude smaller, have negligible lift, and stay in suspension long enough to travel the length of an irrigation run.
Do nano-bubbles improve water infiltration?
Nano-bubble infusion changes the gas content and interfacial behaviour of the water rather than its bulk viscosity. Infiltration and wetting-front behaviour are reported in field and glasshouse work but depend heavily on soil type, water chemistry and irrigation scheduling, so we describe the mechanism rather than promising an infiltration figure.
Are nano-bubbles used in CEA and hydroponics?
Yes. Controlled-environment agriculture, hydroponics and vertical farming are the most common settings for nanobubble equipment, because the nutrient solution is recirculated and closely monitored. Hydrogen nano-bubble infusion is applied the same way: inline, on the pressurised side of the pump, ahead of the distribution manifold.
How stable are hydrogen nano-bubbles?
Nano-bubble stability is a function of size distribution and surface charge, not of the gas alone. Because the system infuses immediately before the emitter, retention time between injection and delivery is short by design, which is why the delivered concentration at the dripper (3,000–5,000 ppb) is the figure we specify rather than a shelf-life claim.
Can nano-bubbles be used in turf management?
Turf and golf irrigation is a standard nanobubble application, typically through the existing pressurised distribution system. Hydrogen nano-bubble injection integrates the same way, inline at the pump house, without changing sprinkler or valve hardware.
What is inline nano-bubble injection?
Inline nano-bubble injection means the generator sits within the irrigation line itself and infuses gas into the flowing water under pressure, rather than treating water in a holding tank. It is also described as pump-inline dosing, and it keeps the treated water travelling straight to the emitters.
How do nano-bubbles support root-zone conditions?
Because nano-bubbles remain dispersed rather than venting, gas reaches the root zone with the irrigation water instead of being lost in the line. Oxygen nano-bubbles act on root-zone oxygenation; hydrogen nano-bubbles introduce a reducing species into the same zone. Both are mechanisms of delivery — site response depends on crop, substrate and water chemistry.
Can nano-bubble systems be used for irrigation water treatment and remediation?
Nanobubble equipment is widely used in irrigation water treatment, aquaculture oxygenation and water remediation. The HERO Irrigation system is a hydrogen infusion device: it adds molecular hydrogen to the water and does not disinfect, filter or replace an existing water-treatment or filtration stage.
