Securing optimal water quality for fish farming in land-based facilities is key to provide the best possible growth conditions.

The Mainstay Weda is a subsurface cleaner developed for easy and frequent improvement of water quality.

It’s designed to clean tanks, both vertical and horizontal surfaces.

Mainstay Weda operates with a minimum of manual work and in the gentlest possible way for the fish through the entire growth period from smolt to ready to harvest fish.

The remote controlled Weda is made of epoxy coated aluminium and has a plastic cover with no sharp edges. 

The vacuum technology makes it stick to the surface and allows the collection of mud deposits, algae and debris through a discharge hose or through a filter.

It’s equipped with two IP cameras and lights, enabling continuous inspection and recording of the cleaning process.
