Kossy, one of our former mods, used it and recommended it highly. When I tried feeding it to baby corys, they ate it with great gusto, but in a very short time I found little fuzzballs on the bottom of the tank.
I think it's important to use just a very tiny bit of it and dissolve it as thoroughly as possible, to achieve good results. If you plan to keep corys at the bottom to clean up uneaten bits it might work out well for you.
