    Hi guys. Ironically this isn't for my SW tank, but my new FW tank. After going big with the SW I upgraded the FW from a 40 gallon long to a 120 with a 45 gallon sump. Everything is running flawlessly right now (its only been running since Sunday), but I can NOT for the life of me get the flexible vinyl tubing-the clear stuff-to stay put. Since the tank is planted and injected with CO2, I'm trying to keep surface turbulence to a minimum, and I'll get the return nozzles where I want them, and duct tape (yes I've resorted to duct tape), it to the back of the tank, and it just pops off and moves to where it desires, which is not where I want it.

    Are there any hidden tricks to keep it to stay put?

    try heating the vinyl tubing up, like putting it in hot water for 10-15 minutes. makes the vinyl soft and managable.
