Hard-to-clean small tanks and other aquariums benefit from the light flow rate in this battery operated siphon. Waste is collected in the attached mesh bag while water and beneficial bacteria is circulated back into your aquarium so you don't need to change more water than you'd like.
For my larger tank I have a EHEIM which works pretty well, just need patience. This one I use in my smaller tank and it really doesn't do well but again patience. It is not one I would really recommend.

The first time I used it I thought it was ok but this time, not so. Maybe I needed a deeper tank. No matter what way I used it it just stirrred it up and didn't suck it up. Do not recommend at all.

No matter how I held it, it would suck gravel up into motor. It's unusable. Came with poor operating instructions. Never could get it to do what it's supposed to do. I got rid of it.
