It's also using poor-boy equipment (minus the LED's) and the whole system is kind of a franken-system.... But man do they ever make it work wonders!

I don't doubt no water change can work for certain tanks. But regard this particular tank, I have doubt about its long term success. Long term in my book is 5+ years. The reason I said that is because he is using a bunch of additives to help with CA, Mg and Alk. Those additives have containment for sure. They may not kill your tank in a year or two, but leave the containment accumulated and they may cause trouble.
It's been speculated that a lot of old tank syndrome (melt down of old set up tanks) are caused by build up of heavy metal (although no scientific proof).
