Risks, I dunno.  I used about 2.5# in a ten gallon (with .4# laterite
and 2.5" coarse aquarium gravel).   It is a sword plantlet growout
tank.   It is doing well.  It did have a serious bloom of green water
and bg algae in the beginning, but short-lived.  The afternoon nap
for the lights seems to be very hard on the bg algae.   Thanks to
whoever mentioned it.
