I'm setting up a 180 and am trying to decide on substrate. Will be a birchir tank, but I would like to have the option to grow a couple hardy plants in whatever substrate I go with. My teugelsi enjoys the plants in the tank he is in now so I would like to keep a few. Some cheap PFS would be convenient but I would be willing to pay more for a nice black sand or something like that. If anyone has a similar setup can I get some advice please!
