So I just picked up a 45 gallon long aquarium. I have 2 other aquariums in the home that are all gravel and I was wondering what peoples experience using a sand substrate. Does it even look good? I plan on going with a planted tank in the future so I am going to be adding a small layer of organic soil below the sand. The sand that i have(which ive used in my other 20g aquarium for a beach front) is a highly washed and aquarium safe sand. I have a huge bag of it and was thinking I may go complete sand for the substrate. Does anyone have any pictures of a nice looking tanks with sand bottoms? Or maybe sand is a bad idea. Let me know opinions please.
