"Don't own a BiOrb or Cube, but have bought two of these over the past year for regular aquarium maintenance and they work beautifully. I don't understand why more manufacturers don't include the squeeze siphon starter like this one, as it makes the job SO much easier. Two screw-on ends allow you to adjust the length for a shallower or deeper tank, and both include a built in grate to minimize gravel and (UGH!) fish being drawn into the vac."
