Metal toxic to water

[zenwatergardens]

Hello- anyone know if Chinese made bamboo fence that is held together with pin nails that appear to be a lightweight soft-ish metal like tin or aluminum would be toxic to fish?
I’m planning to place over top to deter geese from thrashing pond again and am concerned that while it won’t be under water the runoff from heavy rains will leach into water.

No clue on toxicity of the nails in such a small amount. I think a lot of aluminum soaking in a pond is not good but not sure about your amount.

Welcome to the forum. I agree with j.w., likely not an issue due to the small amount. Here is a related thread regarding galvanized stock tanks, which would I suspect result in a much higher level of any toxicity than your nails. https://www.gardenpondforum.com/threads/tombstone-pond.32164/#post-508122

yes seems like a small amount would enter water from runoff. Thanks
