I have never ran a reactor in any of my nano tanks and have been reefing since 2005 with great success. Heck, I don't even run a skimmer on my nanocube. No sump either, since it's an AIO. Check out my tank threads for more details.Could you please tell us what kind of reactor or Media you use for your tank?
I'm asking this from some of you guys cause I want to build a nano tank and I want to use your experience.
Thank you
