I have learned a lot from Glenn's info on the "Dutch synthetic reefing" site. It's easy to find on google and if someone wants to go waterchangeless it is a very good place to start learning how; its also just good reading to understand our tanks - there's a ton of wisdom in there.
THE INTENTION WAS TO EDUCATE PEOPLE, THAT THERE ARE MORE WAYS THAN WHAT PEOPLE ARE USED TO.
MAINSTREAM IS FINE FOR MOST, BUT SOME PEOPLE NEED MORE, THAN JUST JOINING THE HURDLE.. I AM ONE OF THOSE...
But it is something you really have to figure out for yourself, in my opinion. This method is not like the zeovit or triton style where you pay for several mysterious potions and if it didn't work it is because you should have bought one more magic bottle. Precision testing is required, as well as the chemistry knowledge to figure out which fertilizer from the hardware store will be safe and raise the particular trace element you need.
I ONLY APPLY TRANSPARANT PRODUCTS, SO I KNOW WHAT WILL, OR WIL NOT BUILDUP IN MY TANK.
It's cool stuff though. Like if people are willing to put in the time to track down his site and learn about the various components they are hugely rewarded. The payoff is a remarkably affordable system with significantly reduced impact on strained water systems. But it's not an easy fix or something you can just go out and buy.
I MADE EASY ACCES AVAILABLE ONLY IN HOLLAND...
Personally, my favorite part is the money. I don't like how bourgeois some reefers can be. They act snobbish like if you can't afford an expensive controller this isn't the hobby for you. Glenns tank is a good example of what's possible by educating yourself instead of taking expensive shortcuts (livestock might be a different story, but I imagine that he pays for a lot of stuff just with frag selling if he needs too) and the info is free for anybody that is willing to go after it. That's so cool.
