If I bought a powerhead from someone who had hair algae problems, would I necessarily be bringing home his problem?

The powerhead in question was out of water for a number (?) of days. I saw the coraline on it and thought it may seed my new tank, right? Every little bit helps...

But this greenish fuzz developed instead in a day so I yanked the PH back out, scrubbed it off and threw it in the garage.

Could it seed my tank in an unwanted fashion?
