Sand is the trap that ruins most gravel vacuums: a normal siphon just sucks the sand straight up the tube. For a sand bottom you want a siphon you can hover just above the surface, so it lifts the light detritus off the top while the heavier sand drops back. Look for a wide, controllable nozzle and a way to throttle the flow.

A few things separate a good aquarium vacuum for sand substrate from a frustrating one: hover, do not dig, wide nozzle, flow control, and prime easily. Weigh these before you buy.
- Hover, do not dig: hold the intake just above the sand so debris lifts and sand drops back.
- Wide nozzle: a larger intake mouth slows the flow so it will not grab sand.
- Flow control: an adjustable valve or pinch on the hose lets you tune the suction.
- Prime easily: a shake or pump primer beats sucking the hose by mouth.
