Coarser/pebble substrate over dirt?
Would this work? My 50g is thriving with black diamond cap over MGOCPM, but I have a bug up my butt to do a 20g low-tech pea puffer tank in the near future. I'd love something with a different look from my heavily planted, jungle-like tank with dark substrate...something maybe lighter-colored, small pebbles.
