I'm getting algae growth in the greenhouse. The glass is easy...I just
squeegee it when there's condensation on it. My problem is on the aluminum
and brick.

Should I worry about it? What should I use to get rid of it?

I spray the glass, benches, and walks every week with one percent bleach. I
make no effort to keep any splashing off of plants. I have seen no problem
after doing this for about 4 years. It certainly keeps the algae under control.
I picked this up from Geo Vasquez, at Zuma Canyon Orchids.
