Arg! It has happened to me at last - my 10 gallon tank has been overrun with a strange green scurge. One weekend I did a fairly large water change, to eliminate some cloudyness, and the nex thing I knew I had green water so dark you can't see the fish unless they are right next to the glass. It's been almost two weeks and I have seen no improvement (I'm not even doing water changes cause I'm scared it will get worse). Do ya'll know how to get rid of this nasty water, that doesn't require starting over? (because I simply don't have time) ??? ???
