Instant Amazon

A visit to a pet store during my once a month trip to the city gave me
a chance to check out some new, (to me), products, and Instant Amazon
caught my eye. I've seen some of Marc Weiss's ads in aqua magazines,
and the label on this bottle of magic potion is downright verbose, but
it doesn't really tell me a whole lot. It looked like a cure-all tonic
sold by a traveling snake oil salesman. I was looking for a black
water supplement, so I bought a bottle. Now, can someone tell me why
this is better than, say, the old standby Black Water Extract? From
your experience, (I'm thinking of Elaine here, but anyone is welcome
to jump in), how does it affect plant growth, biological filtration,
disease (ich) prevention, spawning readiness,etc.

(My monthly visit to the city has been to the tobacco store, where I
can provision my pipe tobacco needs for half the price it costs here
in this little coastal village. Now I get to add a pet store visit to
the agenda.)
