Aqueon Siphon Vacuum Gravel Cleaner Large - 10 Inches...

Sucks up the gunk. Cant complain. No more mouthfuls of nasty fish water for me!

Thisi does work well, and a little too well, for smaller media. Has a hard time separating detritus from smaller grains due to SUCKIN POWER. Also due to this, it will empty a tank quickly. Pretty decent for how much you're paying and how simple it is, but having a smaller tube one for finer work is probably necessary.

The Vacuum works great. However it has a very strong chemical smell of cheap plastic that fills the room wherever it is stored and smells pretty foul when using it

A wonderfully simple and easy to use tool for maintaining a healthy aquarium. Use this unit for both a 20 and 8 gallon aquarium. So simple, just place the hose clip on the side of your drain bucket, place the end of the hose into the clip to keep the hose from accidentally falling out of your bucket, place the vacuum tube into your aquarium and start the flow by gently shaking the tube up and down a few times until the flow starts. I pinch the drain hose to adjust the flow rate as I maneuver the vacuum tube around the substrate of my aquariums. The design of this unit also insures you do not accidentally suck up your tank inhabitants since the tube is intended to remove water and detritus from the substrate and not in the open water column. Highly recommended for great aquarium husbandry.

It works great! I have a 40 gallon tank and a 55 gallon tank, the 40 contains 3 hatchling turtles, the 55 contains a 1 year and 3 month old snapping turtle that I rescued. She is a pig lol makes such a mess, she's about 6 inches in diameter. Now this vacuum sucks up water nice and fast but not so fast that you can't get all the sludge out before it drains the entire tank empty. It sucks up some gravel just enough to loosen the sludge and syphon it out of the gravel then gravel falls back to the tank floor, not to mention it didn't clog up on me, not once. I am very pleased with this vacuum. I've tried others and they either empty the tank too fast, or they get clogged because the suction is too strong and it sucks the gravel ALL THE WAY UP the tube and gets clogged at the top.... (Which is extremely annoying) I've tried other vacuum's and most of them are all just terrible. Some won't even start syphoning! Even if you try and suck it through with your mouth. The size of this is perfect! The diameter of the tube opening is and inch and a half, where most others are 2 inches (unless you're using a mini) I HIGHLY RECOMMEND THIS VACUUM FOR ANY TYPE OF AQUARIUM! Whether you have fish, turtles, whatever.... If you have no substrate on the bottom of your tank it'll work, if you have gravel substrate, great! If you have even SAND I would still recommend this vacuum. It has a powerful suction but not so powerful that it'll suck all the sand out. Hope this review helps someone! I rely on reviews just as you all do, I try to leave my most honest opinion possible to ensure you guys have something to read so you can make your purchase with knowledge of the item you're buying!
