I was advised that I could use sand as a primary layer and then gravel on top to save cash on gravel. I have had good luck with my cories reproducing to the extent that I had to go to a 55 gallon tank. I have heard cories like sand but it can look dirty if not vacuumed daily, which I want to avoid. I also heard that sand if not agitated a bit over time can have bad results. I want to save money and all but not at the expense of the fish or being chained to a vacuum and dont want to damage my filter. Any Ideas?
