The 8 Best Salt Meters
We spent 24 hours on research, videography, and editing, to review the top options for this wiki. Testing and adjusting salt levels is an important part of maintaining any body of water. The correct salinity in ponds and aquariums can make the difference between having healthy or sick fish, and tracking salt in your hot tub or pool can prevent skin irritation. We've rounded up the meters that make it easy to ensure your water is just right. When users buy our independently chosen editorial picks, we may earn commissions to support our work.
