It's not as effective maybe as a gravel vacuum maybe. Some ppl prob already do this.

1 meter hose
asphyxiator (that bulb thing that you can squeeze air)

Actually, one doesnt even need an asphyxiator. One can suck the air from one end so the water will flow.

Same concept yeah? Syphoning the water?>?>?


I did this years b4 I even knew there was such thing as a gravel vac!!! Used it 4 a huge glased bowl we have outside
