rangergirl77 Posted March 1, 2014 Report Share Posted March 1, 2014 ADVICE NEEDED! A few months ago, my large cichlid smashed a cheap glass thermometer. I found the glass, but all the little metal balls fell underneath my gravel. (and they are too heavy to be vacuumed up!) Today during a gravel vacuuming, I noticed the floor of the tank has rust & the balls have disappeared. I tried to scrape some of the rust off with a algae scraper....but it didn't come off. So I just recovered the area back with gravel.Is rust hazardous to my fish? I'm worried! Quote Link to comment Share on other sites More sharing options...
Jayba Posted March 1, 2014 Report Share Posted March 1, 2014 I wouldn't worry too much about it. Rust isnt toxic, if you do frequent water changes and use prime/safe you should be fine. Quote Link to comment Share on other sites More sharing options...

jvision Posted March 1, 2014 Report Share Posted March 1, 2014 Some people who do the layered substrates for plants will put some nails in the bottom b/c they figure as the nails rust, they'll add iron to the water for their plants. I'm not really sure of the validity of their biology/chemistry, but I haven't read of many (if any) negative impact. Quote Link to comment Share on other sites More sharing options...
PistolPete Posted March 1, 2014 Report Share Posted March 1, 2014 (edited) Same thing happened to me. Haha the Rust never left. Bothered me so much I swapped tht tank out. I no longer use that type.

madagascariensis Posted March 1, 2014 Report Share Posted March 1, 2014 A little too late for you, but when it happened to me I tied a magnet to a string and problem solved. Quote Link to comment Share on other sites More sharing options...
