You are 100% true! Ever wonder why silicon tubing turns red with some sort of dye, like food coloring? Or Watter Wetter???
Vinyl tubing you can simply clean it off, with silicon you dye your water red, expect your tubing to be red too. Actually more of a pink, since silicon tubing is kind of an off white.
