I would like to add some to my system. Does anyone have some they can part with or know where I can by them.
I understand they filter the fish waste and leave the plant roots alone.
i've seen them on ebay a few times as well
TC, did you introduce them? If yes, where did you get them?
At my old house I did introduce a small bag full of them but I never saw them again there.
It wasn't until I had a raft bed set up at the new farm that I started seeing many of them. I'm fairly sure they came to the new farm from the old farm in among my pond plants.
I don't remember who I ordered them from (I think it was a place in North East Florida) but I haven't been able to find their web site. The Ladies at Green Acre Aquaponics might know of a source you can order them from.
I will caution that if your system water doesn't have a certain amount of hardness (calcium carbonate) the critters may not thrive because they need the calcium carbonate to grow their shells. I have really hard well water so it is actually difficult for me to get my system pH down to 7 especially during the dry season when I can't top up with rain water.
I found them from a company in Lakeland on ebay.100 cost me 15.00 with shipping. He was selling a mix of all kinds of little things so I asked him to send me only scuds. I found ghost shrimp at my local petsmart. I was thinking of adding them to my swril filter.
