So I am messing around with a bunch of ideas for my 40g that I will be building, and I know everyone has an opinion about this, so
I'm trying to decide if I want to go with a 2" sandbed, 4" sandbed, or even just go bare bottom with black starboard to protect the glass / maybe try to grow a GSP lawn on the bottom
I know the biggest issue with doing a bare bottom tank is that you can get really bad buildup at the bottom. Aside from that, could there be any benefit of doing it this way?
Also, if I did go with a sandbed, is there any downside to using black sand?
