1 handful non-iodized salt

Over time, mineral deposits and other buildup can make the inside of your fish tank look a little cloudy. And what’s the point of having fish if you can’t enjoy watching them? Because fish are especially sensitive to environmental pollution, it’s best to avoid harsh chemicals when cleaning their tanks. Instead, use a small handful on non-iodized salt to scrub the glass clean. Make sure to rinse the tank well before refilling it.
