This produce came available to me at the time I set up my second show tank. A 75gal. I was looking for something that wasn't a hassle to use like other substrates and had nutrients for plant growth. I was tiered of using root tabs and need an alternative. It was expensive but I got a deal form my LFS when I ordered six cases (12 20# bags) I didn't use all of them in the 75gal but at the deal I got was planting on using it in other new set ups in my aquarium room. I must say this has been a dream come true for me. I would recommend  this for any one who was looking for substrate in a plant tank. ON rinsing, high in nutrients, cuts down on tank cycle time. I like it so much I replace the old substrate in tanks that I have all ready been setup for years. This stuff really grows plants.
