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.
