I wanna keep my calcium levels easily maintained on my 150gal. I was wonderig what would be better if at all. A kalk reactor or calcium reactor. And what are the associated equiptment that I will need along with those two.
A Calcium reactor would be better overall. Once it's going it will run for a long time with no maintenance.
The Kalk reactor is less complex but requires servicing a lot more often to clean and add lime.
