ChuangLan Aquarium Cleaner, Aquarium Cleaning Pump Kit for Fish Tank, Aquarium Vacuum Siphon Pump Adjustable Water Flow Controller for Changing Water and cleaning gravel 2.4M（Gift sucker）

This works so well. Have had other more expensive types before but this is much better. Pump means suction starts easily and is so strong. Only negative is that some of the connections are loose and we will need to tape them to make it secure.

No instructions and a cheap extension pipe but overall good product. Does job.

excellent syphon really long. use on 350 litre tank. two or three squeezes of bulb and syphon starts. gentle on sand. really great bit of kit.

The plastic pickup that goes on end of tube and into gravel/sand keeps falling off, so can only use the tube to clean/syphon

Saved me so much time, bit tricky at first but once you get used to it it's brilliant.

Brilliant,save getting mouthful of aquarium water and does the job brilliantly 👍

Doesn't work on 50 ltr or small tanks

Good product and easy to use
