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..

      Sir,
      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.

      Regards

      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?

      Regards

      Hi Murray, I would like to get rid of my aquaponic systems. Moving to Brisbane and will be renting... 2 x IBC with one grow bed each and a blue barrel system with two grow beds. Operational for 2 1/2 years, 25 Jade Perch(+/- 30cm) with a few blue claw crayfish.

      Hi planning on setting up a system in Goolwa SA,
      I want at least 6 grow beds and would like to have fish all year round,

      would I be better off having 2 x 3000Lt tanks - one with larger fish and the other with small fingerlings, so that I can have fish growing to plate size at all times?
      Also , would it be best to place the tanks side by side and cover with a small shed ??

      any advice appreciated

      cheers Jan

      How do you deal with plant pests?
      How can you safe guard the fish in the system from toxins?

      Hi, Murray, Would there be any ill affects to adding a cup of Greensand into my 5 gallon Dutch Buckets with a grow medium mix consisting of 3 parts Perlite to 2 parts Vermiculite to 1 part Coconut Coir?

      Hi Murray, just a thought I'd share with you....For any newbie the use of abbreviations can be off-putting, if not confusing... perhaps a section with abbreviations and their meanings could be of value to the forum.

      Hi Murray, I am in Brisbane, and looking for a local source of expanded clay. Can you sell it to me? Otherwise, can you recommend a source, preferably north side of Brisbane, or possibly Gold Coast region where I travel.
      I have one IBC unit ready to go, another unstarted, & two 120mm by 3M PVC pipe beds under construction. Hope you can help me with this, Thanks!

      Question: If you have a high flow rate in a dwc system, can you increase the number of fish you are stocking in your grow out tank? I know they have the 2:1 or even 3:1 ratio you can follow but shouldn't flow be a determining variable as well?

      Hi Murray,

      Good to hear from you. We are wanting the Barramundi for a commercial aquaponic operation, will they work?

        Hi Patrick,
        Yes they will work, but there are easier fish to start with. Barra have a bad habit of eating their brothers and sisters.
        I hope this helps

        Regards Murray

      Hello Murray Sir,

      I was indeed humbled by your visit to my small Aquaponic Research Farm located on what one calls "wasteland" and where I am researching "sustainable urban aquaponics" and trying to, and have I believed, incorporate numerous methods of aquaponics growing styles, you being masters on one, "media beds". My small Hybrid aquaponics system is one that is ideally suited for not only the "Micro" backyard gardener but one that can also have commercial applications. This view is taking ground as it is what could be the basis of acceptability by many a "micro backyard gardener" as well as others...just read the recent article on this;

      Hi Biggles not so easy to do with fiberglass. Bulkhead fittings are much more convenient when working with glass and shipping beds all over the place. I love what you have done and is a really good DIY build.

      Hey Murray, I tried something new with my latest grow bed. Since the thing is plastic I welded a high pressure HDPE pipe instead of using a bulk head fitting. Works like a charm. I'll never use a bulk head fitting again. Afterwards I was thinking about your grow beds and though that although it's easy enough to silicon a bulk head fitting, it may be possible to mould the fitting in or something similar. Just a random idea. I'm aware that because my GBs are all plastic it was a simple task.
