What are ya'll doing for Calcium

[ratboy]

Kalk reactor w. peristaltic pump. It binds phosphates, buffers the pH at night when I dose, adds Ca and replaces my evaporated water.

Calcium reactors are too much hassle.

I've found it much better than mixing up kalk. I just fill it up, set the bubble count and let it run. No need to adjust or changing anything. The only thing I hate is have the CO2 replaced. I think the 2nd chamber makes it more stable.
