Practical Aquaponics and Integrated Aquaculture Technology
Murray Hallam is probably the best-known face in the world-wide Aquaponics movement. Murray is by nature an innovator and in his Research & Development facility has perfected many new methodologies for commercial farm Aquaponic systems.
At Practical Aquaponics, we have a range of information suitable for the novice to the expert. Browse our blog, register for our Aquaponics Courses, Workshops and Seminars or buy kits, books, DVDs and many other aquaponics necessities in our shop.
Proven and tested, there are hundreds of our kits in operation in every state of Australia and we have exported our kits to the USA, Hong Kong, New Zealand and Nassau. The wonderful thing about Aquaponics is that almost anyone can participate and get to grow some clean, healthy vegetables and fish.
Everything you could possibly need to set up an Aquaponics farm or home system is found in our online store. Whether you are looking to do Aquaponics in Brisbane, Perth, or anywhere in between, we’ve got you covered with the best range of products Australia-wide.
Our Aquaponics Photo Gallery is constantly growing to include images from Murray's Global Aquaponic Trips, Commercial and Home Systems, Greenhouse Tours, Master Classes and of course the all-important produce in the Practical Aquaponics section.
Our Blog contains a wealth of information spanning a wide range of Aquaponic topics, from general news to some of the well-kept secrets to success. This is a must view area for everyone interested in Aquaponics from the budding beginner to the seasoned aquaponics farmer.

In a properly functioning aquaponics system, the pH naturally falls. This is caused by the activity of the bacteria that break down the fish wastes into plant food.
The ideal pH range for an aquaponics system is 6.2 to 7. When pH gets down to about 6.4, it's time to start adding some buffer - that is, an agent that will raise the pH back up to the higher end of the good range - like potassium bicarbonate!
As well as raising the pH, potassium bicarbonate (KHCO3) also adds some potassium (K) to the system, which is necessary to plants but not produced by the aquaponics system itself. Fruiting plants like tomatoes and cucumbers particularly need potassium.
This potassium bicarbonate comes as fine crystals that readily dissolve in water. Mix the necessary amount (instructions on pack) with some water and add the slurry to the system at the farthest point from the fish tank; under the water inlet to the farthest media bed is a great place to put it.
When adjusting the system pH, GO SLOWLY! Never try to make large adjustments quickly; that can shock your fish.
Once your system is up and running, buffering (raising) the pH becomes a routine part of your maintenance schedule, so keep some potassium bicarb on hand!
As long as you keep it dry, it lasts for years, so why not stock up today?
