Wow this almost comes off condescending.
Btw your "with additives" "without additives" pictures are a joke, you showed a part of a tank with what looked like hc and a part that may have had no plants and compared it to a tank that obviously has a hair grass carpet...
Those plants behave so differently you can't even compare them.
What is even the point of this post? It seems like we have this additive drama in almost every single thread that Frank talks about them and it's useless. Frank is detailing here how he sets up a tank with the full ADA substrate system, and how it works for him. If you don't want to Believe In The Heart Of the Penacs, Yugi! you don't have to, just use regular old AS that's been proven to grow plants well over and over. Frank says the full system works better for him, and you know what, I believe him. He's only set up almost a dozen tanks using ADA substrate and presumably has a pretty solid comparison point for with and without additives by this point.
