phosphates

I have a 20 gallon tank. It's been up and running for about 3 months now. My diatom bloom has all but disappeared. My new thing is I've started to notice what I think is green hair algae in a few spots. I asked my LFS for some advice on what I can do to get rid of it. They told me that I should check my phosphate level because if that is high, you will never get rid of the algae. I do 25% weekly water changes. My ammonia, nitrite, and nitrate levels are all at 0ppm. I haven't tested for phosphates yet. Is it possible for me to have a high phosphate level even though my water parameters are good and I do weekly water changes ?

For only being 3 months old I must say I'm impressed to read your nitrates are at 0ppm .

Thanks.
I guess the 25 % weekly water changes help plus I have a protein skimmer as well

Yes and here's how. If the water you put in is not RO/DI then it's possible the original source of water contains phosphates. You should get a test kit to test the water before you put into your tank. If you are using tap water then chances are high its from there.
