I have a 1500 gallon pond with koi and goldfish, I also have a 6' x 6' bog that the water from my pond is pumped into and after it filters throught the bog it spills back into the pond. I would like to use a copper sheet formed around treated lumber as a spillway from my bog back to my pond, I have read several articles that say you can and you cant use copper. If I cant use it, is it possible to cover it with lacquer or something so that it wont corrode?
Please help asap.
