I had alkalinité and calcium swings.

You probably didn't have an SPS heavy tank then. If the Ca stops for a day or two in my tank, it drops like a rock. Just last week I ran out of Ca buffer for what couldn't be more than 2-3 days. In a 120g system, my Ca went from 400 to 160. It's a pretty big deal. Stability is key and the whole point of a Doser.
In the end, like most everything, you get what you pay for.
