I've scrapped the plan to use the 7/16" ID 11/16" OD tubing I had ordered since I am going to go with compression fittings for this build. Lucky for me this lesson only cost $30 in unused tubing. (Note to self - thoroughly read and reread posts on this site before ordering... )

Instead I'm going with PrimoFlex 7/16"ID 5/8"OD Blue Tubing. I was going to use pentosin for blue coloring/anti-algae but I hated the buildup on the tubing that developed after a month. I like the idea of using distilled water with a silver strip. Much easier and cleaner.

I've ordered all the components so now I wait...
