As most people here know I am not a lover of sand....Partly because I have always used UG filters...Well, till about a year ago when I started a long term test and have two tanks without them. Anyway, we have a 150 gallon tall that was going to be a salt reef. But after three years and a rather high amount of medical bills I do not have the money for the lights and other gear. So I am planning to do a FW with it. I am going to go sand. Now, I was wondering if I could get some input on this. I am thinking about going black. The cost of high quality bagged sand for a 150 planted tank is a bit high. I have no experience with blasting sand but have heard that some have issues with it having sharp edges. I plan to have a large school of corys. So, what do you sanders think?
