First, pop the lid off your brine tank. If the salt looks like a solid, gray brick of doom, break it up with a broom handle—gently, like you’re angering a sleeping bear.
You should see salt sitting above the water line. If it’s lower than a few inches, add more salt. Pro tip: use high-purity solar or evaporated salt. The cheap stuff is just a future headache in a bag.
And never, ever overfill it. Two-thirds full is the sweet spot. More salt than that, and your water might start tasting like a pretzel.
