By scenario
| Scenario | Amount |
|---|---|
| 1" shallow / aesthetic bed | 10 lb 1 × 20-lb bag. No denitrification. Acceptable for SPS frag tanks. |
| 2" standard sand bed (most reefs) | 20 lb 1 × 20-lb bag. Best look-to-maintenance ratio for mixed reefs. |
| 4" deep sand bed (DSB) | 39 lb 2 × 20-lb bag. Provides anaerobic denitrification. Old-tank-syndrome risk after 5+ years. |
| Bare bottom | 0 lb Frag tanks, ULNS, maximum-flow setups. Best detritus visibility. |
