Gravel Cleaner, Small

It's good to use

Sturdy construction, high quality materials. Works as intended.

Purchased this on my wife's account, but putting the review on mine. Hence no verified purchase. What has a guy got to go to get people to believe him these days? Anyway, I digress. This thing is top notch. We have a Top Fin 10 gallon starter tank complete with a few real plants and Johnny Depp style pirate decor, with a top fin premium gravel base (see tasteful picture attached, complete with Mickey Mouse Platy and Blue Dwarf Gourami hiding at the back). The vacuum has no pump - it works purely on the wonders of physics and air pressure by creating a siphon. You submerse the empty tube completely in the tank and work out all the air (wiggle it around a bit). Then you put your thumb over the end of the small pipe to stop the water coming out, put that end into a big bucket below the level of the aquarium, and hey presto, water starts siphoning out of your tank. Don't take the big end out, and start to gently vacuum the gravel. It will suck up some of it, but with a little shake the gravel will all fall down again and only take the light dust and other detritus with it. Once the bucket is full or you have removed enough water (25% is good) you can lift the small tube above the level of the tank to stop the flow. Then take it out if you have finished, or empty the bucket and start again. Our first few weeks of ownership we lost 3 guppies because of steadily increasing nitrate levels (we were over-feeding), and also because we didn't have a vacuum. Two weeks of cleaning the gravel using this little beauty of a contraption, and we're back to safe levels. We did a 25% change twice a week, and learned a lot about the delicate bio-chemistry that exists in a fish-tank. The amount of dirt sucked up each change was pretty incredible, even after such a short time. You see it billowing up the tube. Guppies by the way are like the canaries of the aquarium - you only have to look at them the wrong way and they'll expire. A bit traumatic but nonetheless a good life lesson for younger kids. Anyway, can't fault this at the price. Well done Python people.

By far the most excellent Syphon I have used. Definitely worth buying! Make sure you check that the size you get is suitable to the size of your tank but I think every fish keeper should own this

best product and cheap in case you have planted aquarium

Purchased this product after watching demonstrations on Youtube. It took a while to arrive from the USA but it came well packaged and arrived slightly before the scheduled arrival date. I purchased the large version as my aquarium is quite tall. Having tried quite a few cheaper products to clear debris from the gravel in my aquarium, this has to be by far the best. The collection tube is just the right size to maintain perfect suction. Just enough to pull out organic debris from the gravel but not too much suction to pull out the gravel itself. The hose provided is perfect for the job. It is wide enough to create the required suction but soft and pliable enough to allow you to control the flow out of the aquarium. This makes the whole unit very accurate in targeting the desired are on the floor of the tank while you control the flow by pinching of the outlet tube - hence you can remove a lot of debris without emptying out the tank too quickly. All told, I am very impressed. And while it seems like a lot of money to pay for a relatively simple device, there has obviously been significant effort and thought placed into its design. I would definitely recommend!
