Re: Gravel vacuum?
You can get all types from small to large...Some are hand activated, others are water powered such as the Python...It's basically a hard plastic tube with a clear rubber hose attached...You put the end of the hose in your bucket and hold the tube in your tank, turn it to get the air out and shake back and forth to start the suction...Then turning the open end to the gravel you push the end of the tube down into the gravel and allow the suction to remove the water and waste from the gravel. You know it's time to move the vacuum when there is no more debris coming up in the tube....Just move to another spot and repeat until you've removed the desired amount of water that you wish to change...I vacuum 1/3 of my gravel each week and change about 30% of the water at the same time.
