I'm not picking on you here...I'm just thinking out loud about what you mentioned others saying.
Though I guess they weren't really comparing the effects to CO2...just noting an improvement in the plants after implementation of the Hiatt method. Perhaps they had grungy water, and the improved water quality/clarity/light penetration helped a bit? Aside from that, I'd probably be happy to use Hiatt, but find a used CO2 setup for the plants...or do a DIY one like I did years ago. From my experience in FW (over 30 years..yes, started young), I've yet to see anything that would produce lush growth in planted aquariums except true CO2 addition.
