First off, the brown slime algae is caused by light getting into your rez. It has to be light tight or else you will always get algae since algae are plants too, and if no light gets in, no algae can grow.
I have been growing hydro for 2 years now with 5 successful harvests in that time, and I have never had algae problems.
Now as for your plant, it might stress it out a little and stunt its growth to be switched from the environment it was used to growing in, to a completely different growing medium. However it should live.
