Does anyone know if these metals are ok in a fish tank? -- Generic aluminum window screen mesh -- Chrome plated, stainless steel food drainage tray: e.g. https://www.centralrestaurant.com/Steam ... f4QAvD_BwE I was presuming that food safe meant fish safe, but the chrome plated tray is already rusting a little... Thanks so much for your help! |

Aluminium - NO Chromium - NO Stainless Steel - OK Rusty Iron - OK |

Thanks. Is it possible to note your reasoning or the source of your information? I'm sure you're right, I'm just trying to understand everything... |

Many metals are toxic to fish in very low concentrations, an internet search will turn up lots of references to papers about the subject. Stainless steel is non-reactive with the water found in AP systems, so the toxic-to-fish metals it contains don't leach out. Here's some info about rust in water: https://corrosion-doctors.org/Experimen ... mistry.htm - it isn't very soluble. A bit of contact with rusty Iron wont put much Iron into the water, but you dont want a large area exposed. Quote: Chrome plated, stainless steel food drainage tray... I doubt there is such a thing. Stainless steel doesn't need Chromium plating, and wont rust unless of poor quality, due to exposure to AP water. |
