Moss Tank - Need help
I'm going to be setting up a moss scape pretty soon with just rocks, moss, and sand.
I'm going to use flame moss, mini pelia, mini fissidens, java, christmas, etc.
Will I need to have substrate in my tank for beneifical bacteria? Or will it be ok to just affix the mosses to rocks and wood and have the sand in the front part of the scape?
I'm going to have co2 and medium-high light.
