Mainly, oxidizing bacteria cause slimy strands and similar-looking sticky substances. The most common is iron bacteria and sulfur bacteria. There are other similar bacteria that create slimes. If you notice pink rings, a Serratia bacteria might have caused it.

How or why does it actually happen? Iron bacteria are commonly found in well and groundwater sources. They use dissolved iron or manganese present in the water to grow. Mild temperatures and low-level of dissolved oxygen help in the growth. 

The bacteria produce by-products, such as slime, debris, rust, etc., while growing. Sometimes, iron and sulfur bacteria can coexist in private water systems. This makes the slimy problem even worse! In such a case, you will face heavy slimes in the water tank, toilet bowls, and other similar places.

How Can You Detect Slime-Forming Bacteria?

How Can You Detect Slime-Forming Bacteria

If you notice reddish, brown, yellowish, orange or gray-colored slimy strands inside the toilet bowl or toilet tank – this is the first sign. It indicates that your water source might have slime-forming bacteria/iron bacteria. 

For a second thought, you can notice the taste and odor present in the water. Do you notice smells similar to swampy, rotten vegetation, rotten egg, sewage, or cucumbers? There might be iron bacteria. To detect the odor effectively, leave the water unused for several hours.

Another culprit in forming slimes is sulfur bacteria. To detect the presence of sulfur bacteria, look for rotten-egg odor. Sulfur bacteria produce hydrogen sulfide gas in hot water. The gas smells like rotten eggs. These bacteria produce dark-colored slimes. 

If you have a magnesium rod in the water system, make sure to replace it with an aluminum or zinc rod. Then check for the rotten-egg odor. Why? Because an anti-corrosion magnesium rod causes a chemical reaction in contact with hot water. The chemical reaction often produces hydrogen sulfide gas. So, change the rod to get the correct result.

The last and final step – test the water of your water sources for the presence of iron and manganese. A few labs specifically test for iron and sulfur bacteria. You can get that test done too. This way, you can detect the presence of slime-forming bacteria correctly.
