None of the truly awesome 'no water change tanks' are truly that way to the letter. They will, and do, change some water, just not on regular schedules. They are truly limited water change tanks. The only ones that have been running for a long time (years and years) also work very hard to do other things like supplement and test - Dutch Synthetic comes to mind, but it costs more and takes more time than changing water for most folks, so it is more of the lifestyle than a cost or time saver.
I also question the people who don't do them and say their corals look great. Not question, but I'm guessing they are mostly LPS and softy tanks that require much less maintenance
