Need Opninon on this CO2 Product

[herns]

Natural Aquarium Vital

This product looks interesting as additional CO2 supplement, in addition to my Excel and DIY dosing for my 20G planted tank. Does anyone use this product before? any advice out there before I make my purchased?


Thanks in advance for all your opinions.
