Green Algae on glass

[reef dude]

My tank has been up about 7 months now. I used to get a ton of brown algae blooms but stopped after i used a phosphate sponge that brought .5ppm down to .1ppm. now i am getting green algae thats spreading rapidly all over the glass. what do i do???

scrape it- and get about 15-20 snails- green algae is normal. Dont over feed- do waterchanges and replace bulbs when needed- 3 good things to remember
