Oxygen is the first thing to crash during treatment and the last thing fish can live without. Oxygen Cone keeps dissolved oxygen where it needs to be.
Where it really pays for itself is high-density fish farming oxygen supply. That is the exact failure point behind several of the conditions in our library, so addressing it directly shortens treatment time and cuts re-infection.
How to use it well
Supersaturation improves disease resistance in commercial settings. Treat it as part of a protocol rather than a magic bullet — it works best alongside good husbandry and the medications matched to your specific diagnosis.
Conditions it helps with
On our disease pages you’ll see this equipment recommended for conditions such as:
- EUS
- Whirling Disease
- Ceratomyxosis

Care & Usage Tips
System Design & Installation
- Size the cone to your peak oxygen demand at maximum stocking density
Oxygen demand in aquaculture scales with biomass, water temperature, and feeding rate. At 82°F (28°C), tropical fish consume roughly 250 mg O₂/kg/hr at rest and up to 800 mg/kg/hr post-feeding. Size the cone to supply peak demand at your maximum intended stocking weight. - Always pair with a dissolved oxygen controller and alarm
An oxygen cone delivers oxygen in a closed system — without a DO controller, supersaturation can develop rapidly, causing gas bubble disease. Set the DO controller to cut off oxygen supply at 120% saturation as an absolute maximum. - Install a pressure regulator on the oxygen supply line
Oxygen cones typically operate at 2–5 psi. Oxygen cylinders deliver 2,000 psi at full charge. A two-stage pressure regulator is not optional safety equipment. (Ref: NFPA 55, Compressed Gases and Cryogenic Fluids Code) - Locate the oxygen cylinder in a ventilated area
Oxygen enriches combustion and dramatically increases fire risk in a confined space. Store cylinders outdoors, in a ventilated shed, or in a purpose-built cage. Never store near heat sources or within 20 feet of flammable materials. - Purge the system with water before first oxygen introduction
Air pockets in an oxygen delivery system create intermittent oxygen pulses rather than steady delivery. Fill the cone and all supply lines completely with water, then slowly introduce oxygen flow while monitoring the outlet DO probe.
Operational Safety
- Inspect all fittings and connections for oxygen leaks monthly
Oxygen leaks are both a fire hazard and a system efficiency loss. Use oxygen-compatible leak detection solution — never oil-based products, which ignite in pure oxygen atmospheres — on all fittings. Tighten or replace at the first sign of leakage. - Monitor DO continuously — not just at scheduled intervals
Oxygen demand fluctuates dramatically after feeding and during disease events. An inline continuous DO probe with data logging is the appropriate monitoring solution for any system using an oxygen cone. - Train all staff on emergency oxygen shut-off procedures
In a commercial setting, every person who works near the system must know where the cylinder main valve is and how to close it. Post laminated emergency procedures at the cylinder location. - Clean the cone body quarterly to prevent biofilm buildup
Biofilm inside the oxygen cone reduces oxygen transfer efficiency and harbors pathogens. Drain the cone, flush with a dilute citric acid solution (2% by weight), allow 30-minute contact time, then rinse thoroughly before returning to service. - Replace O-rings and seals annually
Rubber seals degrade in high-oxygen environments faster than in air. Annual seal replacement on all O-ring joints prevents both leakage and the sudden, complete seal failure mode that can dump an entire cylinder’s worth of gas.
