Sponge Back Drop
I have just been given a 120cm bow fronted aquarium which had two ghost carp in it, at the back of it is a sponge decorative screen which I think also has a bottom filter in it, also has three or four air line going into it.
I would like to keep tropical fish, so could you answer the following questions.
Is this sponge backdrop ok to use.
How should I clean/sterilize it if it is
There are two small digs on the front acrylic glass, they feel as if there is something stuck on it, can I polish them out.
Thanks for looking.
