you could start dosing that stuff at 3ml a day and it should have the same effect as Zeo :mrgreen:

Thanks. Not sure but think the big softener theye installed will remove up to 5ppm but of course thats just a rating. I will ask him to look inside the toilet tanks. I know when they purchased the place, it had no filtration on the well, so the systems were getting raw well water before and there are likely iron stains still from that. They have replaced most of the taps and so on.

When I was on a well, my large particulate filter, {same model}, had a lot of crap and sludge in it at change time but never red like theirs.

If it is not iron bacteria and just iron it will depend on if it is ferrous or ferric iron in the water. An water softener will only take out ferric iron, if it is ferrous he may need a chlorine injector or a chemical free iron filter to get rid of the iron. It sounds like ferrous if there are stains on the fixtures and trim. The iron is oxidizing as it comes into contact with the air, turning it to ferric iron and staining. Just my thoughts.
