I love it, I thought it wasn't that cheap but the 5lb bucket I got was way too much and I could have got less, but it grows plants like crazy. I only have a 41g but its sloped almost 5 in to 2.5 in back to front and I have a good amount left over. I put in root tabs when I first set it up (about three months ago) but havent since (have been forgetting to do it) and all of my plants have taking off. Even some that I got within the last month. I would recommend rinsing like it says or your tank will be cloudy for a couple of days, but goes away otherwise i really like the stuff.
