I seriously considered making one of those. I thought it was the coolest thing ever. But the clear PVC tube is difficult to find around here and my tanks are not at the same level. One is slightly higher than the other so the lower-level tank would constantly flood. The setup I have right now is basically the same principle. Water chemistry is the same in both tanks due to the shared wet/dry.
