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.

An EC meter (Electrical Conductivity) is a device that measures the electrical conductivity in the water and therefore is an indication, usually of salts in the system water.
EC measures salts, or total dissolved solids (TDS)
Almost all Hydroponic solutions are salts and therefore accurate measurements in a HYDROPONIC system can be read by noting EC readings. Hydroponic nutrients can be added to a Hydroponic system very accurately by using an EC meter.Not so in an Aquaponics system. Our nutrients are not salts, so EC readings are only a very, very broad measurement of nutrients in an Aquaponics system and should not be taken too seriously, except when they do get too high, you should ask yourself, "Is there salt in the system? And, "where is it coming from?" Common salt can build up over time from various sources such as the use of low quality fish feed, or if you live in an area where ocean winds can carry salt into your system.
Generally, we do not like too much salt in our freshwater Aquaponics systems because food plants do not do well in salty water. Most freshwater species of fish can tolerate salt very well so it is not a problem for the fish. It is the plants that one would be concerned about.
An EC reading is also very useful if you need to have sick fish treated with salt in a hospital tank or quarantine tank where you would add salt to the water to treat the fish. In that instance a very accurate measurement of the salt added can be made with an EC reading device. Using salt to treat sick fish is one of the few ways we can treat fish that we plan to eat someday. It is not too desirable to use veterinarian type medications on fish we plan to eat someday.

If you EC gets above 1 in an Aquaponics system you would need to start looking to find out how salt is getting into your system. As per the short article EC is of no consequence in an Aquaponics system. If your EC gets above 1 start looking to find what may be the problem.
