Ok....I'm curious. As some of you know...I'm going to be putting together a new tank...well not new, a transfer but anyway. I may not transfer all of my substrate that is white sand. I've seen some tanks that were black sand and I have to tell you .... they were awesome looking. I have an opportunity to purchase 90 lbs of black sand and I'm wondering what the pros and cons would be of black vs white? Any comments are appreciated.
