More Surface Area
Many small bubbles provide more combined gas-to-water surface area than a few large bubbles.
Turn ozone gas into a dense stream of fine bubbles for more even distribution through water. This ozone diffuser stone combines a porous 50–60 micron body with a durable stainless steel barb for a secure tubing connection.
The diffuser is designed for compatible water ozonation systems, replacement applications, and ozone generators that require a fine-bubble stone for preparing ozonated water.
An ozone generator creates ozone gas, but gas generation alone does not prepare ozonated water. The gas must be delivered beneath the water surface and divided into bubbles.
Bubble size, diffuser placement, tubing fit, water depth, water temperature, generator output, and operating time all affect how ozone contacts the water.
A fine-bubble ozone diffuser divides one gas stream into many smaller bubbles. This creates more combined surface area and helps distribute ozone through more of the water rather than releasing one large concentrated stream.
Many small bubbles provide more combined gas-to-water surface area than a few large bubbles.
The porous stone spreads ozone throughout the water instead of releasing one concentrated stream.
Fine bubbles generally rise more slowly and remain in contact with water longer than large bubbles.
Improved diffusion can reduce ozone that immediately escapes as oversized bubbles.
The 50–60 micron pore range helps create many small bubbles as ozone gas moves through the diffuser body. Rather than releasing ozone from an open tube, the porous material distributes the gas across many small openings.
Distributes gas through many openings to create a broad bubble pattern.
Provides a durable and corrosion-resistant connection point for compatible tubing.
The textured stone body supports fine-bubble gas release across the diffuser surface.
Some ozone may still leave the water as off-gas. Pair the diffuser with the Tri-OXY REFRESH Ozone Diffuser & Degassing Kit when you want a coordinated system that diffuses ozone into water and routes excess gas through degassing material.
The diffuser introduces ozone gas beneath the water surface and divides it into fine bubbles.
A degassing system manages ozone that rises out of the water without dissolving.
Prepare ozonated water for fruit and vegetable washing routines.
Prepare water for use on compatible food-contact tools and surfaces.
Use freshly prepared ozonated water on compatible household surfaces.
Prepare ozonated water for compatible plant and garden uses described by the generator manufacturer.
Use in compatible water-treatment setups where fine-bubble ozone diffusion is appropriate.
Prepare ozonated water for compatible non-medical cleaning applications.
Use with suitable ozone equipment for small-batch water applications.
Replace a clogged, cracked, contaminated, or poorly performing ozone stone.
Use clean compatible tubing without cracks, stiffness, discoloration, or split ends.
Slide the tubing fully over the stainless steel barb until the connection feels secure.
Position the diffuser near the bottom of the container to maximize upward bubble travel.
Confirm that bubbles appear evenly across the stone before continuing the ozonation cycle.
If the tubing is difficult to install, gently warm the tubing end with warm water or low heat, push it fully over the barb, and allow it to cool before use. Do not overheat or damage the tubing.
Greater water depth gives the bubbles more distance to travel before reaching the surface.
A partially exposed diffuser may produce uneven bubbling and reduce water contact.
Avoid pressing the diffuser against the container wall so bubbles can spread freely.
Water contains dissolved minerals. When water remains trapped inside the fine pores and evaporates, mineral deposits can form inside the diffuser.
Over time, those deposits can narrow the pores, change the bubble pattern, restrict gas flow, or completely block the stone.
Remove the diffuser from the water immediately after the ozonation cycle.
Continue flowing ozone gas or clean air through the stone while it is out of the water.
Continue gas flow until visible moisture has been expelled from the pores.
Allow the diffuser to dry fully before storing it in a clean, protected location.
Always remove the diffuser from water and blow out retained moisture after use. Mineral blockage caused by improper care may prevent the stone from working properly during the next session.
Smaller pores may be blocked, forcing gas through fewer larger openings.
Gas escaping from only one area may indicate partial mineral buildup.
Check for clogged pores, kinked tubing, loose fittings, leaks, or reduced generator output.
Inspect the generator outlet, tubing connection, check valves, and diffuser for complete blockage.
Routine drying is the most important maintenance step. If visible mineral deposits begin forming, follow the cleaning instructions for your ozone system and diffuser material.
Do not scrape the porous surface with metal tools, drill into the stone, or force sharp objects into the pores.
Hard scraping may damage the porous body and create an uneven bubble pattern.
Do not use cleaners that can remain inside the pores or contaminate future water.
If gas flow cannot be restored or the stone is cracked, replacement is the safest option.
Hard water can leave deposits inside the pores more quickly than low-mineral water.
Blowing water out after every use is the most important step for preventing blockage.
Drops, hard impacts, freezing, or crushing pressure can crack the porous stone.
Oil and unsuitable liquids can coat the pores and permanently reduce gas flow.
Oil can coat the internal pore surfaces and prevent ozone gas from moving evenly through the diffuser.
Once oil enters the porous stone, it may be difficult or impossible to remove completely.
Oil can line the internal pore structure and reduce permeability.
Coated pores may produce weak, uneven, or oversized bubbles.
Oil residue trapped inside the stone can contaminate later water applications.
This diffuser is not limited to one ozone generator. It may be used with compatible ozone generators that provide the appropriate gas outlet, tubing size, flow, and intended water application.
Confirm compatibility before use. Too much pressure, incompatible tubing, or incorrect fittings can reduce performance or damage the system.
Add fine-bubble water diffusion and excess off-gas management to a compatible ozone generator.

Water should never backflow into the ozone generator or electrical components.
Use tubing intended for the ozone application and sized for a secure connection.
The porous stone may crack if dropped on a hard surface.
Protect the stone from moisture, dust, freezing, and contamination between uses.
Ozone gas can irritate the respiratory system. Use ventilation, keep ozone away from the breathing zone, and follow the operating instructions for your ozone generator and degassing equipment.
Use this diffuser with a compatible ozone generator, or choose the Tri-OXY REFRESH kit for coordinated water diffusion and excess off-gas management.
