Does anybody have any insight on what substrates are good for Low-Light Low Tech aquariums?
Dirt, Sand, BioFriendly Gravel?
IMO some kind of "dirt" is best. Whether this means ADA's expensive aquasoil or a Wallstad set up is less important though:
There's a ton of info on "dirt" over in the substrate section of this forum. I'm thinking of doing a walstad-type set-up and topping with ADA (cause I like the look of it) for my next tank.
