Hello all. I have been using all aquaforest products in my mixed reef tank since I first set it up about 4 years ago. I have never been able to understand the use of Bio-S and Pro-Bio-S. I understand they are beneficial bacteria that are supposed to out-compete harmful bacteria. In this sense, is Pro-Bio-S very different from Microbakter7? If yes in what way? Would there be some reason to use both, or one over the other?
