Some what of truth in here!
This comment relate to both, I used to be a Pro Athlete back in the days and only perfect workout makes a good workout.
But a workout without a nutrient diet is not making you reach your limit.
That said is basically what ZEO is about, I talked to several German greats in the marine hobby and ZEO is nothing else than just give your corals per dose the right nutrients and food for them to perform on a top level.
Everything is balanced out but still need some tweaking by the hobbyist for their system, not every system is the same.
Coming back to AA, I bet that ................ 80% of the hobbyist don't know what AA is doing to your corals and why you use it other than getting the awesome colors.
Are all AA the same................. not really.
Just read this article from Tim Wijgerde,
Aquarium Corals: Amino Acids and Corals: Sources, Roles and Supplementation ? Advanced Aquarist | Aquarist Magazine and Blog.
It gives you a better understanding what AA are for and why to use it.
Just believing and following other hobbyist and don't know what you're doing and making a statement that it isn't working doesn't make sense.
Not saying here that I'm a PH-D on this level, but if I want a piece of the pie I'm always looking not to get the whole pie but the recipe.
Only than you can share your experiences on a larger scale.
I know this is kinda deep but it works for me if you make it your own.
Btw, I did slowly stop the ZEO challenge.
I had awesome results and I know it's working but I was ready for a different challenge.
And in year maybe sooner I'm ready to take on another challenge to try out on my system, heck I'm already doing it on my frag system that I have setup.
