I am on a well and just installed a water softener and a Omni filter. out of curiosity I wanted to see what I filtering away from. When I took the filter out the contianer was full of a floculant brownish slime. I attached a picture for you to look at to help Identify it. It is odorless and floats around in the water very well and does not stick to itself. Is this iron bacteria? My toilets are not slimey and have no smell. Thanks for any help.
