I'm planning on having sand/substrate in my 75 gallon tank and was wondering what kind of sand/substrate I should use? I was thinking on using the flourite black sand, the CaribSea Aquarium Substrates, or the flourite substrate.
If you have a tractor supply near you. Go grab some bags of black diamond blasting sand(coal slag) 8 bucks for a 50lb bag used it in my last planted tank looks great and works well. Play sand and pool filter sand are also good
