The byproducts are going to likely be as you have stated proteins and enzymes as these are all much smaller than the bacteria that produced them. To remove those things you would likely need to use a charged vehicle that would bind to said proteins and enzymes and then filter them off as a larger aggregate of molecules.So, that coincides with the testing showing no bacteria is present at all.
Yet, UWC says right in their ingredients "Cultured Bacteria Blend".
The testing shows same as AlgaeFix when ran through a NMR (think that is what it was called)
Previous testing of QUATS (again, thinks thats what they were) shows the same as AlageFix
So in order to wrap my head around this, all that is left is the below.
UWC stated they used a byproduct of the bacteria. What possible byproduct could that be? An enzyme, a protein, etc?
What would it take to filter that out? Would it be filtered out by any of the previous ones to remove spores and live bacteria?
