Hey guys,
While doing some maintenance today, I noticed discoloration on a bag of carbon I added a few days ago. Initially I figured it was just some bacterial/algal growth but after pulling it out, I'm almost certain it's iron/rust staining.
This bag was added to the tank about 5 days ago. It's a nylon mesh bag filled with Marineland Black Diamond activated carbon, which I've used many times and never had any issues.
I'm not ruling out external contamination either, this bag was placed right before the return chamber in my sump, so it would likely catch any debris from other equipment in the sump or in the tank. Going to start checking pumps, magnets etc. and see if there's anything suspect.
Anyone else ever had carbon do something like this? And is there media available to absorb iron out of the water column?
Thanks.
