I am in the planning stages of setting up a 46 gallon bow front with a 3d background with filter material behind the background.
My question is whether the contact of the water with the styrofoam over time will it leech any unwanted chemicals into the water that will effect my fish and plants? Or should it all be sealed, whatever is in contact with the water?
