We stay until the biofilter works.
Our engineers install and commission the system on site, and stay through biological start-up, the weeks when a new RAS is most likely to lose fish. Then we support the farm remotely.

Four stages on your site.
1
Install
Tanks, loop, oxygen and controls installed to the layout.
2
Commission
Each unit run and checked with water in the system.
3
Biological start-up
The biofilter matures before full stocking.
4
Hand-over
Your team trained on daily operation and maintenance.
What the site must have ready.
Most installation delays come from the site, not the equipment. We send this list with the drawings.
Building and floor
Built to the agreed layout and levels; slab cured
Power
Connected to the agreed supply and voltage; generator on site if planned
Water
Make-up water connected; quality checked
Local crew and lifting
Labour and lifting equipment as agreed in the contract
Equipment
Delivered, unpacked and checked against the packing list
Test kit
For oxygen, ammonia, nitrite, pH and temperature
What we check, unit by unit.
Pumps
Flow and head at the duty point; standby switch-over
Drum filters
Rotation, backwash and level control
MBBR biofilter
Media moving freely; aeration even
Degassing and oxygen
Air flow; oxygen supply and dissolution
UV
Lamps on; flow through the unit
Controls and alarms
Every alarm triggered and received
Why we stay through start-up.
New biofilter media has no bacteria. Stocking too early causes ammonia and nitrite spikes. One filter maker reports that in warm freshwater nitrifying bacteria take up to 30 days to establish, with 2–3 weeks more common, and that saltwater systems may need 60–90 days (). Our engineers stay until the biofilter keeps up with the fish load.Aquaculture Systems Technologies
- Ammonia and nitrite watched daily
- Stocking increased in steps
- Problems fixed while we are there
- Your team learns by doing it with us

Remote video, email and WhatsApp.
Yes. We have commissioned systems in Kazakhstan, Saudi Arabia and Japan as well as China.
It depends on temperature, salinity and method. Weeks in warm freshwater; longer in cold or saltwater. We plan it into the schedule.
Not fully. Stock in steps while ammonia and nitrite stay low. Our engineers set the steps with you.
Yes. Training on daily operation and maintenance is part of hand-over.
It is agreed per project in the contract.
Send your site. We plan install and start-up.
Send species, target output and site size. A first layout comes back in 3 days, free.
