Stabilise your water system, reduce ammonia risk, and protect your stock with a biological approach that works with your system- not against it.

They’re biological system failures.
When organic load builds up, microbial balance collapses.
That’s when ammonia spikes, odour increases, oxygen drops—and fish come under stress.
By the time it’s visible, the system is already unstable.
![Townsville Cc Case Study Ross River Spillway Event February 2019 (1)[92]](https://greenfoodaustralia.com.au/wp-content/uploads/2026/04/Townsville-CC-Case-Study-Ross-River-Spillway-Event-February-2019-192-1200x900.jpeg)
Proven in large-scale fish kill events
Following a major monsoon event in Townsville, over 150,000 fish (~100 tonnes) were lost in a contained water system.
A biological treatment approach was used to stabilise the system and manage the event in place.
140 → 2.05 mg/L
Ammonia Reduction
15.7 → 0.32 mg/L
Phosphorus Reduction
~100 tonnes
Fish Waste Treated
EPA Approved Release
Water Safely Discharged
Water quality was stabilised to a level that allowed safe downstream release under environmental oversight, avoiding full mechanical removal.
The current approach
- Fish removed manually
- Chemicals used
- Buried on-site
- High labour and cost
- Delayed system recovery
A better alternative
- Treat in place
- Accelerate breakdown
- Stabilise water quality
- Recover faster
Designed for aquaculture operations
- Barramundi farms
- Prawn farms
- Hatcheries
- Pond-based systems
Let’s take a look at your system
We’re currently working with a small number of operations in FNQ.
If you’d like, we can come out, assess your system, and identify where risks may sit and how this approach could be applied.
If you want to make small changes, change the way you do things. If you want to make major changes, change the way you see things.
