Sand Substrate Q's

  • We are currently upgrading MFK. thanks! -neo
Sand should pass thru its the main reason to use sand instead of gravel gravel can get ingested and weeeelllll it doesn't always turn out pleasantly.I don't trust hardware "sand" until I have checked it.pool filter sand is good or fine crushed gravel works well too-Anne
 
I have pool filter sand it cost 5$ for 50 pounds of it , it looks really nice and I can actualy stick my gravel vacuum deep into the sand without sucking almost any of it up because of it's larger grain , I would call it the perfect aquarium sand , also it won't harm your bichir at all considering their natural environment is surrounded by sand.
