Looking for some input/help; my tank is suffering a big GHA & Cyano issue

"Brightwell Aquatics MicrōBacter7 is a selective complex of extremely effective microbes and enzymes that rapidly reduces the concentrations of organic nitrogen, ammonia, nitrite, nitrate, phosphate, and organic carbon in all marine and freshwater ecosystems, leading to greatly improved water quality; better water quality typically leads to healthier aquarium inhabitants."


this above can be pretty much said about most bacteria and the job they do , how do i know that prodibio , zeobak or organic carbon dosing doesnt do the same?

i trust brightwell , but do i really know whats being added?

tests on this product seemed to show the bacteria was alive in heavy numbers but didnt show what type, types or foods they consume.
