Octo i know Animal Kingdom is supposed to get a shipment of arago-live, phone the Hillfox shop. Just make sure of the expiry date on the bags if they have. Or better solution is to seed your own from LR chuncks or get some substrate from the guys on here.
I don't even believe that arag-alive works. How can bacteria stay alive with absolutley no gaseous exchange etc for months?
Get a few small pieces (a kilo over all) of good quality uncured live rock (rock that has just landed) and use that on top of your DSB. The bugs on the uncured stuff will still hopefully be alive, and will populate your DSB.
That's really awesome of you. Where are you going so we can meet up somewhere. I drive to boksburg every week or so. So it won't be a mission for me to go to Boksburg on Tuesday depending your arrival time. (Assuming you're landing at OR Thambo?)
