Yeah buddy, vinegar and salt = back to new.

Guy's years ago I bought a bottle of Midnight Blue Fluid XP ULTRA. It's the kind that is concentrated and I mix it 1 part with 3-4 parts distilled. I've used it in prolly 5 different loops, and I have never once had any build-up, corrosion, color fade, or algae. Also It only very very slightly stains the tubing.

To bad you can't get the ULTRA anymore
