Laelr Fish Tank Cleaner, Aquarium Water Changer Gravel Filter Aquarium Siphon Vacuum Pump Water Changing Sand Washing Adjustable Water Flow with Inbuilt Strainer Outlet Valve Pumping Airbag (grey)

This arrived loose in the amazon box with no instructions or label. It was in pieces which was difficult to fit together, for a while I thought it was broken and that it was no good for sand.Once I finally worked out what to do, it was great. I've got the hang of it now and it is vaccuming up the algae and excess food, no problem. It does also vaccum up sand if held too close, but I just swirl that at bottom of bucket and pour it back in when it's dried out.Good value.

Although the theme of it is excellent. It is manufactured poorly. Keeps falling apart whilst in use. I brought some jubilee clips, and that has now solved the issue of it leaking everywhere. Now it is brilliant to use, but it is a chore to take apart.

Simple to use and put together. Only downside is theres no instructions and the box is in Chinese which I don't speak. But it's very straight forward to figure out. It's a bit harder to get it going in smaller tanks but still has good suction to clean the substrate in aquiriums.

Does what it’s meant to do, saves time doing water changes because the suction strong so the water flowed out reasonably quick but easy to control. Very good.

Great syphon, really easy use.Pump gets water going immediately, only problem is the tap fitting on the hose leaks, I have tried tightening it but it still drips from the outside of the tap, so the tap has to be help over a bucket even when closed.

This item is great, its super quiet and powerful. Cleans all the gunk off the bottom of my tank and whatever is floating in the water, doesn't freak my guppies out and takes the stress off my back while cleaning. No need to futz around with a manual pump. It doesn't come with a hose pipe though which was a pity. Need to buy that separately.

cheaply made would not recommend to another

Great product, makes water changes very quick and easy. Just a couple of squeezes of the pump and the water starts flowing, then a quick twist of the valve and the water stops. We are novice fish tank owners and using this product we haven’t spilt a drop (yet :-) )!
