1. The Practical Aquaponics discussion forum has been in operation for the last 5 years...

    We have enjoyed giving this service free of charge however ongoing increasing financial costs of running this service is making it increasingly difficult. Up until now we have resisted advertising as a means of a revenue stream to help run this forum but it has become inevitable that extra revenue is required to run this forum.

    We have introduced a donate button to help offset the cost of running this forum. It is completely voluntary, but if you would like to donate, all donations would be greatly appreciated.

    Thanks Murray..

      Good day. I am new to aquaponics but have been educating myself for six months and am ready to start a community based commercial aquaponics business. I seek guidance in terms of design and size. I plan to: 1. Grow on 280sqm of 30cm deep DWC grow beds(I may need advice on how to harvest 2000 heads of lettuce/week) 2. Harvest 416kg of Tilapia every 6 weeks Any feedback or guidance will be appreciated.

      What answer do you give when out marketing products regarding potential contaminates such as E. coli? I don't recall conversation regarding this during the course. We've researched it and read that cold-blooded animals (fish) don't harbor E. coli or other typical contaminates. What have you all found?

      Hi Murray, I have done my calculations for aeration into fish tanks and dwc as per the formulas in the design course. There is a 40 l/min pump listed in the Indy 11.5 plan set. My figures are 75 l/min for a 1000 l fish tank and 28 l/ min for the dwc Is this because the water flow is providing aeration. I am curious to know , if I can go down from 120 l/min to 80l/min,it draws only half the power.
      Cheers mate

      I am currently in China, promoting aquaponics as I go along. I would appreciate greatly your opinion as to the best way to grow sunflowers aquaponically. I had thought DWC on rafts but I would love your advice.

      Hi Murray, I'm trying to locate a commercial aquaponic farm to ask a few questions in regards to post harvest methods to complete my assignment. I can't seem to find any commercial farms or contact details on the net?
      Would you know anyone in Australia who could provide an answer to my questions?
