Hello I will be building a 3D background for my 75 soon and I'm just gathering supplies. I was wondering if I need any special type of styrofoam. I know some are denser than others and are cheaper.
Also, my local craft store,HD
, and Lowes only have up to 2" thick. I need 3" for my ideas. Anyone know of any local places I can call? Would lumber places or like roofing places have it? Also, the styro at HD
and Lowes I think is made for insulation...Wouldnt this have some type of chemical in it toxic to the fish?
One more question...
If I cant find 3", can I just silicon a 2 inch and a 1 inch together and then cut it up? I wanted to cut it into big individual pieces so I can put it together like a jigsaw, but would that work??
