Comment by Kim Romen on July 23, 2014 at 12:11am: Justin, gardenpool.org sells it

Comment by Jeff S on July 22, 2014 at 7:29pm: Justin, find a pond and you should find duckweed. But let me warn you it doesn't grow like you have read about so don't be disappointed when it under performs.

Comment by Justin Beavin on July 22, 2014 at 4:32pm: Also im in the east valley if that helps narrow it down

Comment by Justin Beavin on July 22, 2014 at 4:30pm: Im looking to acquire some duckweed.... does anyone know where I may get some at? Thanks in advance.

Comment by Timothy Borg on July 20, 2014 at 9:56pm: @Matt it sounds cool but your link is not working for me.

Comment by Matt Miskinnis on July 20, 2014 at 9:23pm: My new addition to my automation: my WiFi fish tank temperature reader. Let me know what you think. Allows you to view your temp via the web, and will also send you email when the temp gets to warm or to cold by triggers you can set.

Comment by Dr. George B. Brooks, Jr. on July 19, 2014 at 4:58pm: P.S. Yes they are cannibalistic and often need shelter such as stacked 3-4 inch PVC tubes for best results.

Comment by Dr. George B. Brooks, Jr. on July 19, 2014 at 4:54pm: Greetings all. Their environmental requirements are much the same as for tilapia but they are not at all cold tolerant. 70F is about the minimum. They don't like copper in the water and since their shells are made largely of an organic version of calcium bicarbonate, probably 6.8 is the lowest that you can go with the pH (need to research this one). Unlike tilapia they don't do as well in poor water quality including needing a reasonable amount of oxygen.

Regarding density, first I would disagree with those who suggest putting them in your IBC. They from my experience will not do well there. However as suggested by many, they do reasonably well in DWC grow beds. Because they are a low density product, you can't get all that many of them into your system at one time. I would suggest 1 prawn for every 2.5 square feet of DWC growbed space for now. Depending on how you manage your system you may be able to do better in time.
