i had wierd black stuff like that on my vals a little while back. I just cut off the areas that it was black. Now its good. :) You could try that. Bubbles, i dont know. Has anything been added to the tank chemical-wise?

[PhillipOrigami]

Nothing other than pure 10% ammonia.
Okay, I'll just cut it back then.

My tank was bubbly on the top like that after I added Pimafix! I just did lots of water changes and it went away. Scared the crap out of me though, I thought my little brother had put hand soap in the tank or something.

I just had all those bubbles on my cycling tank, and my nitrites were really high... I did several water changes and now the bubbles are gone. Maybe the high levels of ammonia or nitrite are doing it?

Hmmm, that could be it...
Removed the plant growths.
