I've owned this AO Smith AO-WH-SOFT-450T for a few years, but this is the first time I let my salt get this low, I noticed the water in the brine tank looks bubbly and murky. Is this just from the salt getting too low or am I looking at another issue here? All of the lines in and out of the unit look secure. Thank you for any guidance.
