Has anyone used coal slag (sandblasting grade) as a substrate? It appears
to be more coarse than silica sand and according to the manufacturer has a
neutral pH. I like the color and was wanting to use it in combination with
laterite in a planted aquarium. I know that Seachem's flourite is highly
rated but am searching for a lower cost alternative.
