Pack 2 Adjustable Aquarium Water Pipe Holder Water Tube Clamp Fixed Clip Fish Tank Hose Holder Aquarium Hose Holder (Blue)

Use your filter pump at its max by avoiding houses to twist up in the corners, excellent

It’s flimsy and it doesn’t work this is a waste of your money

The clamp doesn't get wide enough to fit over the lip of any of my aquariums, so I cannot use this as it's intended to be used. The way that I still get some use out of it is to clamp it to the horizontal inner lip of the tank top rather than the vertical part of the actual top of the tank. If I do that, I can put the siphon tube through one of the two grabby things and it sort of does what it's supposed to do. Just seems like a major design flaw that you basically can't clamp this thing to the top of an aquarium when that's literally the purpose of the clamp.

Will work great on rimless tanks, but isn’t big enough to fit on standard aquariums. I love the concept, but wish it was just a little bigger so that I could securely fasten it to the rim of my tank and not have to worry about it coming off.

Useful when doing the water removal and aquarium cleaning alone as the tube keeps moving

As pictured it would work well with a rimless tank. However, with a rim the fitting is too small.

Works perfectly!

Thought these would work. But we're to small for some of hoses for tank.
