the challenge
The world needs more fish, and cleaner water to grow them.
Over a third of the world's marine fish stocks are now overfished, and for the first time we farm more seafood than we catch. With the population heading toward 10 billion by 2050, farmed fish has to grow, and grow sustainably. Recirculating systems reuse water in closed loops, which makes water quality the one thing everything else depends on.

Sustainable protein
More fish, farmed with less impact.
Water quality
In a closed loop, clean water is the limit.
System efficiency
Less energy, less downtime, lower cost.
Why ozone
Nature's disinfectant, made for closed loops.
Ozone destroys pathogens, oxidises the nitrite and organic load that builds up in a recirculating system, clears the water and keeps biofilm from forming. Then it reverts to oxygen. No chemicals added, nothing left behind in the water your fish live in.
Where it works
Four places ozone makes the difference.
Intake water
Disinfects incoming water and removes colour, odour, iron and manganese, so nothing unwanted enters the loop.
Protein skimmer boost
Our high mass transfer injection lifts skimmer efficiency, cutting ozone demand by up to 30% and stabilising the water.
Heat exchanger efficiency
By preventing biofilm, ozone keeps heat transfer efficient and temperatures stable, lowering energy and maintenance.
Oxygen enrichment
Efficient oxygen dissolution with minimal pressure loss, holding dissolved oxygen steady in fresh or brackish water.
Safe for the fish
The right dose, and never more.
Ozone is powerful, and that is exactly why it has to be controlled. Too much residual ozone harms fish, and in seawater ozone can form bromine by-products. Arrow Lake doses in real time and measures continuously, holding ozone in the narrow band that cleans the water without ever putting the stock at risk.
​
The same system that purifies the water also proves it stayed safe.
The difference
Clearer water. Healthier fish. Lower cost.
Crystal-clear water and low turbidity.
Lower peak nitrite and organic load.
A stable, higher redox potential.
Less biofouling, and more efficient heat exchangers.
Cleaner-tasting fish, with off-flavours like geosmin broken down.
Lower energy cost.
