"Solucalc makes watersofteners based on CO2 instead of salt, and I have to say that this works very good. We used the water 5 days without CO2 because the bottle finished, and my god, we had a lot of hard water 'damage' immediately. So very happy with this easy solution that saves space. We had a very good contact with the sales guy and also during installation everything went super smooth."

"This system is a good alternative if you live in an apartment without the possibility of installing a salt water softener in the basement, as in my case. It works :)"
