Marco rock cycling Q's

[Proteus]

My tank is over run with Collonista snails and asteria stars. Though harmless I do not want them in new tank

I plan on buying new dry Marco rock and cycling it for a few to three months in a tote.
I would like to use my tank water from current DT to help the process.

My Q while silly is this

Can the snails and stars be transfered through the water?

Of coarse I know the adults can't but eggs or other stages of life
