How do you siphon a nano tank?

Yeah a small gravel vac is what I would use. Maybe try to hook it up to the filter so not to lose any water.
 
because it filters the mulm through the filtration....cleans the water, dirties the media instead of losing your total water volume
 
routing your vac through the filter would screen out solids sure, but what about trates? u know, the main reason for water changes...u could do that but u should still do a water change about 30% at the same time, when u have ur old tank water in a bucket, slosh ur filter around in it to get rid of the solid garbage, dont rinse it in tap water because u will lose a lot of ur good bacterias. the key is to get fresh water in there, even if your tank looks like crap you still need good params. dont forget the de-chlor!
