Happens to mine all the time mate. Green algae I get. Not sure what causes it but wouldn't worry about it, it's never caused me any issues anyway.
i've read articles about the algae eating the nute solution that's for my plants! not for some leachy algae... haha But i'm assuming it isnt alot if it does at all since ive had algae for a minute and it doesn't seem to affect anything. I'm just a slightly OCD and don't like it. haha
