I'm onboard with the whole low nutrient thing, I just have a hard time jumping on board with additive systems without seeing many success stories. I am not out to bash anyone, I would just like to SEE more success stories so I could make a better decision that this may be the way to go. I believe each tank is a unique ecosystem and way too many people try to generalize "quick fixes" to improve color, growth, etc. If you are diligent with your husbandry and learn from methods that are proven for others, you have a greater opportunity for success. Lets see some proof of concept - then I'll jump on the train.
