I use pea sized gravel. It doesn't compact and create water chemistry problems like sand. It's polished, so it's fine for a popular fish like Corydoras. The irregular shapes allow for good water flow to allow rooted plants to get proper nourishment. It's inexpensive and easily cleaned so it doesn't cloud the tank water. It's colorful, so blends with whatever aquascaping you like.
Planted tanks don't require vacuuming. The plant and fish material that settles to the bottom dissolves and nourishes the plants. The excess that may cause water chemistry problems is easily removed with large, frequent water changes.
