At Aquaponic Solutions we specialize in the commercial integrated production of fish and plants, known as aquaponics.

We are dedicated to providing the best services and information about aquaponics around the world. Our Director, Wilson Lennard (PhD), is an Australian scientist with a PhD in Applied Biology, with a thesis topic specialising in the optimisation of commercial aquaponics systems. Wilson also has over 13 years of experience in the aquaponics industry; a length of association with aquaponics that only a very few can claim. Therefore, you can be sure that you are getting the very best advice on aquaponics. 

Calculators and Models

Aquaponic Solutions (Dr Wilson Lennard) developed one of the first sizing calculators for backyard, media bed aquaponic system sizing. This calculator allows you to size the plant components (grow bed) of your system based on the inputs of fish tank volume, fish density and the feeding rate. It outputs specific design parameters such as the grow bed surface area required and the required minimum flow rate.

You can also use the calculator to determine the grow bed size for many different fish tank volume scenarios and in this way, determine the different grow bed sizes that match with these.

There is an associated PDF document that explains in full detail how the model works and all the associated assumptions.

Fact Sheets

Aquaponic Solutions has written a number of "Fact Sheets" that explain a number of the components and processes that operate in aquaponic systems. These fact sheets are also made available, free, to you for you own use. Topics include Fish Tanks Shape & Size, Media Bed Sizing, Fish to Plant Ratios, Solids Filtration and Basic Water Chemistry. 

These will assist you to learn about some of the basic and core principles of aquaponics and assist you to be mindful of what is important when designing and managing your own aquaponic system.


Aquaponic Solutions offers a list of services to the aquaponic industry. Core services include the technical design and management of aquaponic systems in a commercial production context. Technical design includes system sizing calculations, fish component design, plant component design, filtration design and sizing, hydraulic design (pipe sizing), mineralisation degn and sizing and flow rate design. Aquaponic Solutions can design commercial aquaponic systems using either our unique Symbioponics design approach or by using adapted, standard UVI feeding rate ratios. We provide full CAD engineering drawings so you can build the system yourself or use a builder. We also design standard recirculating aquaponic systems and de-coupled aquaponic systems. Our approach allows us to fit the design to any fish or plant requirement and we can scale systems to any requirement.

Aquaponic Solutions has been in the business of aquaponic design and management provision for over 8 years and our director, Dr Wilson Lennard has over 15 years experience in the aquaponics sector. We welcome you to our web site and hope you find what we provide meets your requirements.
