Help - which one? Cheap or not
I really like the look of silica sand in small to medium sized tanks, I'm going to be setting up a 46G planted tank with a fluorite/sand 1st substrate layer, I then initially wanted 3-4cm layer of silica sand on top. However reading through the forums and other websites people say it is too fine and compacts. My second option would be something like 1-2 mm Black Quartz Gravel but at £30 ($55) for a 25kg bag I don't know if I can justify it? The 25kg bag of sand cost me £4.
Will Black Quartz be a better substrate for the aquarium and the plants? I think it would be a nice contrasting colour but slightly unnatural looking, sand looks really natural IMO!
Thanks in advance guys.
