Using black polyfoam background

[cheese]

Hi all,

Finally I'm ready to set up my first saltwater tank. The 3.5' tank I'm using was formerly used for freshwater setup, so I have this black polyfoam background bought from aquarium shop, almost same as the type Juwel is selling for their tanks but cheaper and much thicker, sticked inside the back of the tank. It give a much more realistic backdrop as compare to those prints that stick behind the tank.

Hence, wish to check whether can this black polyfoam background be used for saltwater too. Or should I dig it out and remove it totally instead? I'm trying to setup a simple coral/reef tank with some fishes, would this black polyfoam material affect them, or react with the water?

Please kindly advise. I'm struck with it whether or not to take it out for quite some time. Please please help me on this.

Thank you! Cheers!

I have the same black foam background in my tank also, I'm using it for at least 1.5 years already .. so far so good. Only sometimes you will find some bits of black foam floating on the water surface, dont its chemically active.
