Changing live sand

[likwid]

So I tried to siphon out the crushed coral, but my tube is not big enough to get it out, as it plugs up within seconds. I tried to scoop it out as well, but it just causes a huge cloud storm. Anyone know where I can get a rubber tube that is around 2 inches in diameter that I can use as a siphon? Can't be PVC or anything hard, as it must be able to bend out of my tank and into my bucket.
