Superfish 礫石清潔器 S

The intake tube is a bit short for my deep tank, but once I angled it, the gravel cleaning worked perfectly. Really happy with how easy it is to start the siphoning.

The auto-start feature is a game-changer—no more fiddling with siphons. Cleans the gravel thoroughly while changing water at the same time, which cuts my tank maintenance in half. Works exactly as advertised for my 20-gallon.

I was worried about messing up my gravel during water changes, but this 2-in-1 tool handles both jobs smoothly. The suction is strong enough to pull out debris without stirring up too much sand.
