Product Details

The Indy 23 Aquaponic System is designed to be a powerhouse of home food production.

  • 23 sqm (250 sqf) of growing area
    • Four media beds, each 2.4 m x 1.2 m (8' x 4')
    • One raft bed, 4.8 m x 1.2 m (~16' x 4')
    • One wicking bed, 4.8 m x 1.2 m (~16' x 4')
  • Comfortably raise 50 kg (110 Lb) of fish per year
    • Two fish tanks, each about 1000 L (~260 Gal)

Grow just about any type of plants - the inclusion of media beds, raft bed, and wicking bed lets you grow a huge range of crop types.

The two fish tanks make it easy to grow two different types of fish at the same time, or to have two lots of fish at different stages of growth.

This design is the result of nearly a decade of continuing research, trials and actual food production.  As our name “Practical Aquaponics” implies, we have actually built and successfully run productive Indy 23 systems for years. 

Hundreds of people around the world have successfully built this system using the Plan Set.

Building it is fairly straightforward.  Anyone familiar with basic tools and techniques - or willing to have a go! - will be able to build this system.  And the construction uses mostly commonly-available materials, so you don't need a specialist supplier.

The Indy 23 Plan Set gives you step-by-step instructions.

  • Detailed how-to
  • Lists of materials and quantities needed
  • Full-colour photos and diagrams throughout
  • Plumbing layouts
  • Construction tips

As well as the written instructions, the Plan Set includes over 14 full-colour A3 sheets devoted solely to diagrams of the system.

The large (A3), spiral-bound pages make it easy to open the book flat on a work surface so you can check where you're up to as you build.  

Each Plan Set has its own unique registration number, and is personally signed by Murray Hallam. 

If you're ready to commit to feeding yourself and your family, from your own back yard, the Indy 23 Plan Set is for you!


Here is a portion of the Indy 23 plan set that you may find useful.

Site Preparation
Congratulations on purchasing the Indy Fish Garden 23 plan set. The Indy 23 will provide you with an abundant source of fresh food for many years. However, before you get started there are a few things to think about when you start out on a project like this.

1. You will need approximately 16m x 5m (52'6" x 16'6") of space to install the Indy Fish Garden 23. This will allow room for access to all parts of your system, to be able to walk around and work around the system easily.

2. If you live in the southern hemisphere having your Indy Fish Garden 23 north facing is best. If you live in the northern hemisphere then having your Indy Fish Garden 23 facing south is the way to go. If you can't face it that way then it's not the end of the world.

3. We are dealing with a lot of water in the Indy Fish Garden 23 so it is imperative that your site be level. Your sumps, grow beds and fish tanks are open and if your site is not level then you will have water pouring out onto the ground.

4. The Indy Fish Garden 23 requires electricity to run the pump, aerator, failover switch and battery charger. You will need to have it close to an electrical power source, if not you will need to have the power run to the building site from your source of mains power. Please use a licensed electrician if you need to run mains power. The power supply needs to be at the fish tank end of your site.

5. Water is also needed to be easily accessible to fill up and maintain optimum water levels in your Indy Fish Garden 23 whether it is from a dam, tank, well, or town water supply. If you need help from a plumber to get water to your system then please make sure he is licensed.

6. The plans that you have with you are a replication of the system we have at Practical Aquaponics and the dimensions that we have given are what we used to build our system. You do not need to place everything exactly as we have done as we have allowed extra space to have large groups of people through our greenhouse. So when you install your system understand that these plans are a guide for you, but if you follow them exactly you will have an excellent result.


If you want to spare yourself the running around to get all the materials, our INDY 23 FLAT PACK contains all the construction materials needed to build the Indy 23 system (excluding the tanks and barrels), right down to screws, glue and thread tape!  And we can send it just about anywhere in the world.
