It was weird when I first came back to reefing. Once I understood the mechanism (Thanks @Randy Holmes-Farley ) it just clicked. I think afr is a great and very easy product to use with how I am currently reefing. My thoughts may change when/if I have to dose 100+ml.It doesn’t, so I figure I need to monitor and adjust the dosage to fit my tanks consumption.
Weird to me that afr takes quite a while to see all changes
