My Tank Thread
It’s a stand alone product?
How did you manage to draw that conclusion?
AFR is a stand alone product in many tanks if dosed to maintain alk and one is doing normal water changes. There will be a long slow calcium rise, but water changes will mitigate that effect over time.
I know you are focused on trace elements being at some predetermined level, but the evidence for that is fairly weak, and lots of folks are quite happy with AFR along.
