Aquashield isn't beneficial its to help clear out algae and root slime actually will kill your good bacteria. I use great white shark but anything with mycorrhizal in it, like subculture a or b from gen hydro theres a lot of products out there.
Well you are more than a bit off:
"Aquashield Bio-fungicide Water Treatment Solution is a mixture of several strains of beneficial bacteria, including Bacillis Subtillis, Paenibacillus Polymxa, Bacillus Circulans and Bacillus Amyloiquefaciens."
And also, you are sort of talking apples and oranges anyway: the Botanicare equivalent to Great White would include ZHO if talking about mycorrhizal products and not just bacterial. There's just little reason to have a combination product when the application of fungi and bacteria are just a bit different. Not that it makes a huge difference really at the end of the day. I'm sure GW is a fine product itself.
