Pressure Treated Wood around Pond
Can someone please tell me if I may place two pressure treated 2x4s (from Home Depot) on top of my small 4x7ft outdoor pond. The pond contains only goldfish. It will be part of frame and support of a removable screen, placed there against herons. The present one is rotting away.
I thought I read somewhere that the present treating of wood is non-poisenous.
