Black substrate in the Cities?
I have two tanks going up at the moment, a 30g planted community and a 10g planted shrimp tank, and I would like to use a black substrate for at least the shrimp tank. 3M Colorquartz would be preferred, however I could live with "Black Beauty" or Soilmaster Select Charcoal. Would rather not buy "Tahitian Moon Sand".
I will be calling the distributors listed on 3M's site tomorrow, along with some Menards stores. Living in Minnetonka for the summer, just for reference.
Where have you folks found, or seen, these products?
Oh, and I'm going to have a ton of Sagittaria subulata, Dwarf Sag., available real soon. I will not be using it in either of the new tanks, and it was quite invasive in the 15H. Probably two dozen or more plants, some as tall as 6". I am willing to trade for dwarf hairgrass or an equivalent, this will be foreground in the 30g.
