I'm at a crossroads: balling or calcium reactor?
There are many great options for both balling and reactors...
There are a lot of topics, and after the 2nd or 3rd topic, you still don't know what's better...
So the question arises from experience: what is better, simpler, more effective?
Task condition: 700 liters of water. Corals SPS and LPS in equal proportions, for example...
