hyggerUpgrade Aquarium Water Changer Kit, Semi-Automatic Fish Tank Gravel Cleaner, with 25 FT Water Hose, Flow Control Valve

This is a life changing tool, especially if you have large aquarium. Just follow the instructions and you are good to go.

This is only a 1/2" ID hose, so the flow is too slow. It doesn't pick up the gravel at all.I love the integrated valve arrangement and it was very easy to assemble, but the hose should be 5/8" or even 3/4" to have adequate flow.

Mast have devise for big tank.

The hose is too small for the length - it should be a 5/8 or 3/4 inch for anything over 25 foot in length

Easy to put together. Works well. It does suck in some very fine sand so be careful. Much better than carrying buckets!

I don’t use it for gravel vaccum but this product is good for both I have a vaccum already

First, this product is easy to use (after the 1st use), does its job well, and saves time versus the bucket method. The multi-connection adaptor fits most faucets, but it didnt fit mine. My faucet is one of those over-sized models and I need to unscrew the head to access the waterline. Still, the adapters they included didn't fit. Instead, I have found that a clamp-on garden hose aerator adaptor does the trick. You'll see from the pictures how I used it. It's better to remove the washer that was included with the adaptor - it would just squeeze out the top as I tightened the clamp. Hope that helps someone.
