I'm replacing my return pump with something that has more juice, so I figured it would be a good time to replace my return tubing. Right now I have the clear vinyl tube from Lowe's and I hate it because the Frag Tank light in my sump causes algae to grow in the tube, and every time I turn off the return, and the restart, a bunch of algae build-up comes shooting out. Also, I am looking to quiet things down, so here's my dilemma: Silicone return for quiet operation or black vinyl tubing for cleanliness? Or should I go 1' of silicone and the rest black vinyl? looking at 3/4" return line if it makes a difference.
