METAL IN PONDS

[Mmathis]

Back when I had aquariums, I recall reading that you shouldn't have metal objects in the tank. Don't recall why (chemical reactions that could be toxic, maybe?), though. Can you enlighten me?

the best thing i can tell you is that the metal will rust. this could harm the fish.

I recall reading years ago (when I had aquariums) that many of the Rift Lake fish are attracted to rusted steel. In an aquarium, Synodontis catfish will do better if provided with an old horseshoe or other iron scrap, and will pick at it frequently. Perhaps it fulfills some dietary need? I don't believe a small amount of rusty iron or steel in the pond would be a problem.

I hope you are right John cuz I just noticed yesterday while messing w/ a fountain pump that I had a screw on a clamp band that was rusty and was wondering about that. I thought it was stainless when I put it in place but guess not.

The bands on those clamps are stainless, but unless you get the (more expensive) ones marked as SS, the bolts WILL rust.

Well that's what I have evidently and was hoping they would be ok. Only have the one in the pond and pond is 2500gals so should be ok. Iron builds strong bones right or is it good blood?

rust is iron oxide and unless the fish are bathed in it. it is safe and yes it is a necessary trace mineral required in most animals to make blood and tissues.

lead and mercury are what i would be worried getting into my pond.
