I recently had to remove my carbon due to having to treat my tank because of some feeders i bought that had ich. The carbon had only been used for a few days i had the carbon out of water for a few days, can i reuse it or is it toast?
Yes, you can reuse carbon that has been removed. Pixie has a point on the re-infection, but a couple of buck is a couple of bucks. Soaking the pouch in salt water for a few hours should eliminate any risk of re-infection and save you some cash.
