Review on Brightwell Aquatics FlorinAxis: Boost Plant Growth with Carbon Source & Krebs Cycle Stimulator! by Chris Cranor

I use this in place of CO2 in some planted aquariums and in combination with CO2 in others. I currently have 9 tanks with plants, all heavily planted and with a calculated index fertilization schedule. I've seen increased growth and beading on plants. Especially my Hemianthus callitrichoides (HC or CUBA). I am very satisfied with this product. I will be ordering more, but given that you have to put drops in tanks instead of caps every day, this may take some time. Worth the money IMHO.
