Our in-depth look
Who it's for
Freshwater tanks with corydoras, loaches or other fish that sift sand, and anyone wanting a natural riverbed look.
Who should skip it
Planted tanks with root-feeding plants may want a nutrient soil underneath.
Tips
Rinse until the water runs mostly clear, and fill the tank slowly over a plate to avoid clouding. Aim for about 1–2 inches deep.
