What Iron Bacteria Looks Like — and How to Get Rid of It

Learn how to identify and eliminate one of the most stubborn well water problems with help from RainDance Water Systems.

If you’re seeing slimy, orange stains in your sinks, toilets, or water-using appliances, there’s a good chance you're dealing with more than just iron — you may have iron bacteria in your well water.

Unlike standard iron, which can be filtered out by most iron removal systems, iron bacteria is a living organism that thrives in oxygen-rich environments and feeds on iron in your water. The result? Thick, rusty slime and a rotten egg smell that’s tough to ignore and even harder to treat without the right system.

​🧪 What Does Iron Bacteria Look Like?
​You might be dealing with iron bacteria if you notice:

• Slimy orange, brown, or red buildup inside toilet tanks, on faucets, or in filters
• Rusty water with stringy sludge or clumps
• Foul odors, especially a swampy or sewage-like smell
• Biofilm buildup in water pipes or softener tanks
• Reduced water pressure due to slime clogging pipes and plumbing

Unlike dissolved iron, which is invisible until it oxidizes, iron bacteria leaves visible, textured deposits. It can also cause recurring filter clogs and reduce the efficiency of traditional iron filters and softeners.

​🚫 Why Standard Iron Filters Don’t Work on Iron Bacteria
Most well water systems — like basic water softeners or oxidizing iron filters — are not equipped to remove iron bacteria. That’s because:

• Iron bacteria is biological, not just mineral-based
• It can regrow inside your pipes, tanks, or softener media if not properly treated
• It often survives oxidation, even if the iron itself is removed

This means that unless you address the bacteria itself, the problem will come back — no matter how high-end your filter is.
