Worlds largest gravel vac

Rob Top1 · Dec 13, 2014

A friend of mine owns an aquarium maintenance company and one of his accounts is the home office of the local water reclamation. They have two massive native fish tanks, 1500 and 2700 gallons. Every Sunday he puts on his Wadders and goes scrubbing. That process just got a little easier with this siphon. 6" diameter 38" tall and uses a 1.5" drain hose. I think that qualifies for worlds largest but we need to check with Guinness.

Cool, but you would think that would take out too much water too quickly.

You could always siphon it into a filter sock in your sump. I double up filter sock to make sure nothing gets through and do this once per week. No water change necessary.

If he wants to do a twenty percent water change, that's almost 800 gallons of water to be drained out.

How long do you want that to take??

The valve on top will hopefully control the speed of the drain. But with the size of these systems a fast draining siphion isn't much of a concern. I was hoping to go out and see this live in action today but the timing won't work. I've asked for some shots of the filter room and systems as well as a stock list. This system doesn't have a sump but a remote filter room. It was very interesting to visit. Like a behind the scence tour of a public aquarium.
