There is a much easier way to compare. A guaranteed analysis.. every mineral, nutrient, macro and minor. Does this "Wonder tablet" (I can't believe its actually named that) provide a guaranteed analysis? Seachem does. Aquarium pharm. does. Then all you have to do is compare one analysis to another. X provides 3% iron while XX provides 6% iron. X provides 8% nitrogen while XX provides 0% nitrogen. Thats the only comparison that matters. There is no magic bullets. Fertilizer is fertilizer. How else do you know what is lacking if you do not know whats in it?
Tom Barr has been saying this for years. Its the only thing I agree with him on.

I used Ferka Stemma & Rosetta which are also very good.

Another Asian product that is all hype, that gives no information about its contents. I know the company that makes it. They have sent me samples. Guaranteed analysis is a very simple scientific test. It doesn't cost much for a business to get one.
