Water softener tank mould

[lovenaturelovelife]

I have water softener installed in March - Twintec. Everytime salt runs out and Ibreplace the salt- I can see black residue looks like mould in the tank itself. Is this normal ?

Bump

My neighbor had a similar issue after installing a softener, not with a Twintec, but she kept seeing black gunk around the salt area every time she refilled it. Turned out it was a mix of salt dust and minor mold growth from moisture buildup. She started cleaning the tank more regularly and also checked out some maintenance tips online. This guide on water softener maintenance was super helpful for her especially the part about keeping the brine tank dry between refills. Might be worth a look to make sure everything’s working the way it should.
