Thanks, you're a life saver! I was able to find the tubing and a clear water reservoir at home depot, and I salvaged all the T-connectors and 7 valves. The existing tubes were absolutely disgusting, as was much of the rack lol. Even came with a free dead mouseBut I should be okay to set up one rack, which is all I need for the moment. I think I'll put an order in for the valves at that website. Thanks for the link!
