I`m also starting up a basic barrel system. I have many of the same start up questions as Greg as far as shelter and shade. Do we have to be concerned about the rain diluting the system? Currently I`m watching wet snow falling outside. Which brings me to my next big question. What sort of fish will survive in my area?(Sherbrooke Québec, Canada) I know where I can get live Catfish, Tilapia and Troute. The Catfish and Tilapia are both from Chinese grocery stores, should I be concerned with the health of the fish?
This weekend I`m hoping to sort out the plumbing of the system. Our stand is already built. So exciting!
