I bought a water vacuum siphon thing and it works alright to siphon the old water out but it doesn’t vacuum the gravel like I thought it was suppose to? Like I can see stuff floating around after I disrupt the rocks a little bit but it’s only sucking in water and not the debris? am I doing something wrong? Thanks!

Also how often do I change the thing in the filter ?

It’s siphoning water fine but it’s not sucking in debris. My tank is also only a 7 gallon if that makes a difference

Could be the end is too large creating low pressure. You may need something with a smaller inlet..

Or a Python vac that hooks to your faucet for more suction. I actually have small water pumps for removing and pumping back new water.

It has a small ball hand pump to start like the one yours has. Then gravity takes over. I use it on my 10 gallon tank.

The higher your tank is from the bucket the stronger the suction will be
