How much water has been added? How much solution is left? Until now the only way to find out was to measure it yourself.

New to aquarists, and exclusive to Apex, is the ability to specifically measure water depth in inches or centimeters. Available in four different sizes- 4″, 15″ 23″ and 35″ there is a perfect length for water level monitoring in, aquariums, reservoirs, and liquid containers. Take level monitoring to the next level with the LSS.
