Nothing wrong with that; you're lucky it works that well for you, but many times luck is better than expertise.

What's wrong is broadcasting advice that EVERY body do likewise, unless you can also provide them with a working lucky charm that guarantees they get the results you do.

I've never personally tried to floc live goo -- it's worth an experiment. But at present I have no confidence that even 1/3 of the people who followed such advice would get similar results.

Also, less than 1/2 the people here have a working vacuum system . . .
