I used to have gravel and it IMO is much easier to clean. However I've switched to sand and to me anyway it looks 100 times better hen gravel. I had white sand and recently switched because the waste sticks out big time. Ever after cleaning and water change with in a day I could see it. Just switched to black and I wish I had done that from the start. The black brings out the color of the fish and makes the live plants look much better. If you can spend a little more and get you some substrate from a pet store that's made for a tank. With play sand anytime I had to move anything it would get into my filter and ruined both of them. Petco has 20 pound bags for about 15 dollars whoch isn't to bad compared to most.
