okay, so i recently got a piece of mopani wood for my new 29g. i soaked it in a bucked, changing the water daily, until the water was clear. then i put it in my 29 and it was fine for a couple of days. then i went away for a few days and when i came back the wood had this white fuzz all over it and the water was a light brown color. also, the glass has this other white stuff on it. i want to call it algea, but it's white and it sorta hangs off the glass like string, but the string part is only a couple of mm's long. could this be from the feeding block i put in while i gone? please help me, i don't know what to do.
