is it supposed to only take out sea or suck up the waste in gravel?
please help wet change tomorrow!
your suppose to take out water with it, but you can also sort of verbs up the gravel. i got the same siphon and a 10 gallon tank as resourcefully.
It's a good siphon. Put the underpinning under the water, slowly put the tubing under the marine so all of the air comes out of the tube. Once the open tapered tube side is under the water put your thumb over this end afterwards pull it back out of the water, keeping the larger siphon side still underneath water, and move it to a position below the water line of the aquarium, release your thumb and the siphon have begun. The further the small tube outside of the aquarium is below the water smudge the stronger the siphon will be. Since water is moving out of the aquarium use this to your advantage to let the hose suck up the detris and other items sitting on the bottom of the aqurium. If you have true sand you can really only siphon from the top of the sand or it will suck all the bearing up and out of the aquarium, if you have a very small gravel it may stay surrounded by the aquarium and you can siphon further into the substrate. I hope this helps because this is just a basic siphon and as long as nought is blocking the water flow and you are going from a higher water point to a lower point in a sealed environment it has to work. It's basic gravity.
Answers:    Ah yes, Gravel Vac, the best.

Now no matter what subsrate it is its not supposed to suck it up, but with gravel it will pick up the rocks and suck out adjectives the gunk that is mixed in the rocks and suck it out with the dampen for water changes.

But with sand its different. With sand throw away lies on the top (does it not?) and you cant stick the large end in the sand because it will bring stuck.

to clean the sand surface and remove dirty water, remove the large nozzle attachment going away only the small tube.

then create a suction flow and with your fingers, crimp the terminate of the tube to control water sucking speeds. once its at a sucking speed that wont suck up the sand, graze the nozzle over the sandbed and remove the waste lying on top.

And thats all. Your siphone cant not work, its merely a tube. Just need to use it properly!

Hope this helped!

ADDED: yes, it needs to be beneath the water level! D: thats your issue right there. Fine a process to get your tank on a table when you do it?
Place a bucket on the floor make sure the finale of the tubing is in the bucket. Place the siphon in the aquarium and shake it up under marine until it starts siphoning.
Both. Once you inaugurate the water flowing into a bucket or sink (must be lower than the tank... try out a window or down the stairs but you'll probably inevitability a longer tube), you move the tube end in and out of the gravel to remove debris and sediments. The gravel is heavier and should spatter back into tank while the dirt flows with sea up the tube and into the bucket. You may need to pull the tube out of the gravel and towards the surface if you see gravel essential the exit tube (to prevent it from being sucked away). May be a bit trickier with sand.
This also helps you amendment out your water. Don't drain more than half your tank. Add fresh dampen when done. De-chlorinate and condition as necessary.
the out put of the hose has to be lower than the tank and have no nouns bubbles in it
