substrate vacuum

[bapski]

i have a python and a couple of mini-jet powerheads.

can i use the ph to serve as vacuum? will this work? does anyone know how to make this project possible?

the suction of the python should be itself, enough for a "vacuum" - you just push it into and out of the substrate and the detritus should flow up the tube.

for me the suction of python alone is not enough

 

[tbonem91]

is the water level of the tank lower or higher than the output level of the python? The reason I ask is that most if not all gravel vacs are just a syphon - no mechanical or other type of propulsion - the only real requirement is that the output of the syphon be below the water level of the tank and the lower it is, the more suction the syphon creates.

If your sink-driven suction is insufficient or you are "pulling uphill" the best bet might be to use a bucket on the floor and syphon it out for just the vac part of maintenance.

i have the output part of the python in the basement where i mix my saltwater.
