I'm just going to say Aquarium West really hikes up their prices. I got first two bags of eco complete for 52$ each including tax meanwhile it's 30$ at King Ed's not including tax. Also check in with Canadian Aquatics OP they are selling set ups for 5lb Co2 tanks for 265$ I believe said mykiss.I buy it from Aquariums West, downtown, sometimes. Not sure of the price, though. They have a website where you can reach them by email. Or you can give them a call.
