LOL!! I know about the shrimp addiction. I started out with Amanos and now I have those plus the Blues, Purple Zebras and Opae Ula and I'm already looking at more. Haha. If you're already making tons of RODI and feel better about doing that then for sure go ahead with RODI. I do tap for all of mine and so far no trouble but Toronto has really clean water.

You can always try a few with tap to see how it goes if you know your tap water is good. I'm excited for you.

Squeeze the tank in between your other tanks. Maybe your wife won't notice.
