love that its easy to store in plastic container comes with a packet of live bacteria for better roots and faster cycle will not cause cloudiness you can siphon and clean wont hurt barbs on corys like some other more abrasive substrate
I did like it's an easy substrate to stick my stem plants into but they don't really keep them down very well and can easy be uprooted. I would definitely cap this with a thin layer of gravel to be safe.
