national geographic substrates?

  • We are currently upgrading MFK. thanks! -neo
They had 1 bag of carib sea black sand and one bag of the national geographic black sand. Carib sea was 27.99 for 20 lbs the NG was 19.99 for a 25lb bag. The NG didn't even really need rinsed, it was quite clean. The carib sea was a hot mess, took a good long while to get it to rinse clear, sometimes a name is just a name.
