So you have Bio S which is a nitrifying bacteria (takes ammonia and turns it into nitrite, then nitrate) aka cycling. Then you have your Pro Bio S, a probiotic bacteria that takes that nitrate that the nitrifying bacteria created (and some phosphate) and gets rid of it, (thus it takes the nitrate and phosphates an turns it into a biomass). The -NP Pro "minus NitratePhosphate Pro" is a liquid polymer food for that probiotic bacteria so that it can grow rapidly and speed up the process. This "biomass" that the probiotic bacteria creates, then gets taken up by corals as food or the more common thing is for it to be taken up by the protein skimmer.Yeah I actually read the NP Pro description on the AF web site tonight. Trying to figure out how to drive my nitrates up. It says it's a polymer to increase bacterial growth to consume nitrates. So that is very confusing. I will pm you when I have everything figured out for some sticks.
tried to highlight key points but it's all important
