On all of my tanks I have Pool Filter Sand as a substrate. I'm happy with the PFS since it's easy to clean, looks good, inexpensive ($10 for 50 lbs), and the fish seem to like it.
BUT................ I'm thinking about getting a 30 gallon long (30L x 12W x 16H) and using it mostly for tetras. I'm thinking along the lines of Emporors, Columbian, etc. From my "readings" i'm under the impression that these fish would look better with a dark, possibly black, substrate. I plan on using fake plants and rocks.
I was hoping that I can get some options as to what I can use for the substrate that will look good and not be toooo expensive. The less it costs the better I'll like the tank.
Do you have any suggestions ?
