We woke up this morning to find that the brine tank overflowed. We were negligent this last week and didn't fill it with salt. Also, I just installed a water pressure tank and there was a lot of black earth residue at the bottom of the brine tank (and in all the lines of the house) that I have now cleaned out. Should I just put salt in it and regenerate, or is there something else I should do?

Thanks.
