So my neighbour stopped by the other day with a 5 gallon tank under his arm and gave it to me!
He was using it as his Q tank for his saltwater fish, and there's a white film/ crust build up on the inside of the glass.
I went to work tonight and asked what I could do (that wouldn't cost me ANYTHING!) and both the general manager, and the fish room manager told me to use a razor blade on a stick that we sell for 20$
Is there ANYTHING ELSE I can do to take off the white stuff? It's just that this tank is going to be for my breeding tank, and I don't want to salt the poor little babies to death (or kill Pinyin or Ponyo...)
