Okay so i got 10' of vinyl tubing (1/2" ID and 5/8" OD) at Home Depot for less than 5 bucks. Seems pretty flexible to me. I'm going to fit them on the lily pipes with the hot water as mentioned. Now my question is not the clamps on the tubes over the lily pipes, but rather the area over the tubes that connect to the Fluval 106 aqua stops??
