Kalk is great!
I have no hard corals and still keep Ca for my coralline algae using Kalkwasser. I have to put my kalk reactor on a timer now because the Ca was getting too high (500+). Coralline algae wasn't using it as much as I would want. So I'm adding buffer for the alk, and the kalk reactor is dosing 3 times at night only to keep Ca at 420- 450. That way Ca and some Alk are added at night with the Kalkwsser. The buffer is dosed on the 24hr schedule.
The pH goes from 7.9 @ night to 8.3 by afternoon time. Phosphates and nitrates are undetectable. System has only zoanthids and fishes.
I would think Kalkwasser could precipitate some phosphates with the help of the skimmer, but a good maintenance schedule, including partial water changes, is what would maintain the numbers under control.
I believe kalkwasser play also with the organics in the system and help the whole picture.
I really wish I could keep corals!!!!!!!
Lucky guys!
