My system has been up and running for a while now with a dual pump single loop. I've recently decided to change to a dual loop. The tubing in my loop is UV Orange and I was look at adding a second color to the new loop. I'm looking at white but cannot seem to find actual UV white tubing. Everything I seem to find is just white not UV or white but under UV lighting they change to light blue. Anyone know if there is actually UV white tubing? Any suggestions is appreciated.
