Safe Or Not ? Red Sea Carbon Sticking to Magnet

[Minhaj Qazi]

Hi Reefers, I have a 146 gal Mixed Reef which is 2 years mature System and i dont have any Algae etc.
Alk 8.5 dkh
No3 -5ppm
Po4 .10 ppm
Mg 1350 ppm
Tin 25ppm
Salt 1.025
All Other parameters Stable. Less Corals Somehow Receding Continuously Specially Torches etc. Changed 50% water Thrice till i found my Carbon bag rusted as well... what the heck

I was Using Japanese Jacobi Carbon till i Found Rusted Spots on Mesh bag at few places Enough to Deter Me. Picture is attached below. Torches/ Acans Bit Stressed and Found High Tin in icp. Is High Tin due to Same Rusting Carbon or Carbon is Contaminated with Iron or Rusting Metals. Any Other Reason/ Expert Opinion requested..

2. To Avoid Contaminations, I Just Purchased a New Red Sea Reef Spec Carbon 1 Kg and Now Found It Sticking to Magnet as well. Question is ? SHOULD I USE IT OR RETURN IT ? Or Any Technical Details etc if it wont Rust as well. ?

Replies will Be Much Appreciated as I Need to Export Organics Building up in absence of Carbon.

Carbon should not contain ferromagnetic material mabey iron oxide was added to the mix for nutrient export it would explain the magnetism and the rusty ferric material on your mesh bag.
