Nothing original or “modern” here. The recommendation of a 10% water change every 2-4 weeks has been a common practice for over 20 years.
I found the article biased with a lot of claims, lack of any evidence, along with misinformation/half truths.
I don’t see any harm in water changes, but they aren’t the only way to run a reef, and you shouldn’t promote your viewpoint as the only successful method.
<edit: I see now, they are trying to promote/sell a product. Their RKS additive program>
There’s lots of ways to run a reef and lots of tanks that don’t use water changes. I’ve tried many methods over the last 25 years, successfully. I would never say that “method 1” is the only way that works.
Good luck Modern Reef with whatever it is that you do.
If you haven't already, I suggest you research biological doc control via cryptic zone filtration with NPS sponge.
