Ornamental Aeration | Rio AG20 + Sprint

Ornamental Circulation Using a Rio Circulator & Sprint Fountain Aerator

Perfect for large lakes, ponds and water features. This is an ornamental solution that not only circulates and injects oxygen into your water body to control the growth of any algae or aquatic weeds, but also includes a Sprint fountain for an amazing visual display. Combining performance with visual display to maintain a healthy looking clear water. Great for lakes and ponds in farms, nurseries, residential properties, wineries, etc. in which functionality is equally needed as visual appearance.

Lakes and treatment ponds water bodies are typically high in nutrients and become stagnant over time due to a lack of aeration and circulation, which results in an overgrowth of pond algae and weeds. The consequent accumulation of detritus and bottom sludge compounds the problem, and thus, the cycle of stagnation continues.

Step One Chemical Application

Depending on the status of the algae in the water body the use of algaecides may be required at the start of the project to get rid of all accumulated algae or aquatic weeds before the application of mechanical circulation and aeration for long term results. We use a range of algaecides depending on the type of algae in your water body. For more information on the types of algae click here.  Most commonly we use Cupricide, Kupramine or water clear. When submitting your enquiry, please include an image of your water body with algae so we can recommend the best algaecide

Step Two Ornamental Aeration & Fountain

We use a combination of mechanical circulation and aeration to return and maintain the water body in a healthy state. Aeration targets the cause of the problem and yields the best results, whilst remaining environmentally friendly. Essentially, lakes and ponds become stagnant due to a lack of oxygen in the water. The result of stagnation is a bottom sludge of detritus that cannot be broken down. Mechanical aeration reintroduces oxygen into the water column by moving the water, which encourages bacteria (in the oxygen) to naturally degrade the accumulation of detritus. The water clears and begins to return to its natural state.

Step Three Microbial Inoculation

Adding living bacteria that can produce the type of enzymes we need for the degradation of a certain type of algae or aquatic weed. Even if some of these enzymes are degraded, the bacteria will continue to produce them as long as the food (Algae) is available.


Applying mechanical aeration and circulation depends on a number of things including the type of application, the size and depth of your waterbody, the age of the water body and the type of algae or aquatic weeds it has. The use of Rio circulator is perfect for larger water bodies with a total volume of more than 10 Megaliters. Combining multiple units of the submersible Rio Circulator with a surface Sprint Aerator will not only provide the great functionality of keeping your water body clear but also provide you with a fountain for an amazing display. Perfect for larger residential properties, commercial properties (hotels, parks, retirement villages, etc..), Golf courses (near the club house), wineries or farms, where the visual display is important.

Rio Circulator

The RIO AG20 is a water circulator used in applications on larger water bodies to provide mixing, destratification, circulation and aeration, providing environmentally friendly and non-toxic algae control in lakes and ponds. The unit operation maintains constant water movement from the surface to the bed of a water body.

The rotational operation of the propeller is designed to minimise damage to marine flora and fauna and lagoon infrastructure, providing power through a 15:1 reduction gearbox, to allow the large three-bladed propeller to rotate at 115 RPM.

Component Construction:

Central Motor Housing: stainless steel
Front & Rear Motor Flanges: cast iron
Propeller Boss & Blades: cast aluminium.

Sprint Aerator

The SPRINT 1.5 is a surface-mounted aerator which oxygenates and destratifies by drawing water through a central column and dispersing a plume of water skyward. The propeller design allows for dispersal of water both vertically and radially, enabling a greater volume of water to be dispersed into free air, facilitating a more efficient transfer of oxygen to water.  Positioning is carried out by tethering from each of the unit’s four corners to static points on a lagoon bank.

Component Construction:

Motor Housing – marine brass
Propellers – reinforced plastic

Beautiful Fountain Display+ Clear Water Free from algae or aquatic weed

Depending on the age of your water body and the type of algae or aquatic weeds in it you should expect great results within the first few weeks from applying the algaecides. After, when installing your mechanical circulation and aeration system, your lake and pond should maintain in great shape. Toping it all off with a beautiful visual display of the sprint fountain.

Coral Coast Barramundi

Coral Coast Barramundi is located in the beautiful Whitsunday region of QLD and produces high-quality saltwater barramundi. Our farm consists of 24 x 1.2Meg plastic-lined raceways and is a fully integrated system, comprising of broodstock, hatchery, nursery, grow out and packing shed.  Coral coast Barramundi and BioRemedy have worked closely together over the past 10+ years and the  products and services they provide are second to none. Our farm has worked in conjunction with  BioRemedy on a number of aeration, circulation and oxygen injection projects.  In particular, we rely heavily upon the Acqua & Co Force 7.2 as it delivers oxygen injection and mixing like  no other product on the market. The Force 7.2 aerators have allowed us to at least double our production  and achieve excellent Feed Conversion Ratios coupled with the use of oxygen.  Corey Sander, Growout Manager, Coral Coast Barramundi

Rio Technical Data

Standard supply of the RIO AG20 is in an Australian-sourced frame and float configuration and is installed via 3 x 4 mm stainless steel mooring cables shackled to static points on the lagoon bank. Supply can also be arranged for a completely submerged installation, mounted on a structure or concrete slab where it is desirable to completely ‘hide’ the unit.

Maintenance Schedule

The Acqua & Co. RIO AG20 Water Circulator is a heavy duty mechanical unit which is designed for continuous operation in both fresh and salt water environments. Because of its simple direct drive design, in general terms, the RIO has a very low maintenance requirement.

However, it is important to provide effective preventative maintenance to ensure a long life from the circulator. It is recommended that an inspection of the primary seal and bearings is performed annually, with inspection of the secondary seal and bearings performed every two years. It is recommended that the maintenance schedule provided be followed to ensure effective management of your asset.
