    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..

      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.
      regards Mike

      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?
      1. Murray
        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.
    15. Biggles1212
      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.

      Hi Murray,

      I'm having an issue with algae in my duck weed tank. Ive posted a thread but had no takers so far. I'm getting lots of slimy brown algae, but if I cover the tank I will kill off my duck weed. Could you please give me some advice on this? Here is a link to the photo, the thread is in the plant section as I wasn't sure where to post it.


      If I'm flogging a dead horse, I could convert the tank into a wicking bed but I would really like to get the duckweed tank working.
