Using Oil-Dri for cheap substrate?
I am going to set up a couple very low-tech 10 gallons in my basement to hold some extra plants and I was looking for a cheap substrate. I want to try something different though for these tanks. I have heard that kitty litter works well, but is there a difference between that and Oil-Dri?
I also need to add some to my emersed tank so it is not just mud sitting in the open.
