Hi, I've had my tank up and running for a couple of months, first set of fish went in almost two weeks ago, all is fine but I went away last weekend and my housemate looked after the fish (feeding/turning the light on and off) - the stones at the front of the tank and the glass at the front has gone all yellowy. Also some white stones I have in the tank at the front have all yellow stuff on them. Is this just algey? Is there anything I can do about it? I have an algey scrub brush thing which clears the glass but what can I do about the pebbles and big stones? 

Yeah I've checked all the levels and they're fine. I did my usual weekly water change when I got back, it doesnt seem to have got much worse but its no better. I've put a pic of the big stones in, its more annoyin on the little ones and the bits on the front of the tank I can't get to! Any help appreciated.
