Is it toxic to fish? I use a nail with a twist-tie on each clipping of my live Water Wisteria plants. It's to hold them to the bottom of the tank. Then they grow roots and flourish!
Do rusting nails affect the water quality in a freshwater fish aquarium?
They are aren't necessarily toxic, but they do exude mineral/chemical compounds into the water. Depending on the size of you tank you should be okay....unless you have a very small tank and you don't change the water frequently.
Reply:Rinse the nails first, to remove any loose rust. The rusting action is just oxidization and is very slow. The iron is not going to dissolve in the water over night. There is very little iron being intruduced at any given moment. A water changing once a month should maintain the quality of water and is recommended for the sanitation of the fish, regardless. But why rusty nails?
Reply:you should never place any metal in a tank. over time it will erode and kill your fish.why dont you go buy some plastic zip ties (that you use to organize cords behind a tv) or use fishing line instead? or weigh the plants down with gravel or a rock until it takes root?
