Review on Dennerle 4585 Dosator by Keerthi Forrest

I use this with Thrive in a 15 gallon Fluval Flex. My plants have never looked better and I will be buying these for all my other tanks where I can easily hide them. Not the prettiest, but very effective. Update December 15, 2018 I'm getting a few more of these dispensers! I really like how easy it is to use. My plants have never looked better and I haven't seen any algae even though my CO2 tank is empty! I want one for each tank.
