    I know its only Kalkwasser but this unit is just totally FIRST CLASS! I LOVE IT…the simplicity and solid build of it…you can immediately see and feel the quality of it when
    you lift it out of the box and then again when you start using it… Awesome piece of equipment…I am in REEFING since 1989 and its not fun if you don’t buy GOOD equipment.
    You cannot go wrong with this unit…its AWESOME.
