Roof Algae

What is the best way to remove algae and to prevent it in the future? Someone told me about a strip of metal? you can put on the peak of the roof which,when rain water run over it, releases a chemical into the water which in turn inhibits algae from forming????

'carefully' pressure wash to clean. install zinc flashing under the top course of shingles at the ridge. some also say copper works too. i did mine with zinc and it seems to be working.
