I'm confused about calcium reactors vs kalk stirrer's... I know how they both work and the concept behind them but I guess I'm not sure of the chemistry behind them.
I understand that in a reactor the co2 mixes with the water in the chamber to make the ph fall (6.5 - 6.9ish range) then dissolves the media in the chamber; from there drips into the tank replenishing calcium(or alk?)
In a stirrer fresh water is mixed with kalkwasser to create a highly alkaline liquid and the powder at the bottom stays agitated while the 'milky water' at the top gets dripped into the sump. The ph of this liquid is somewhere in the 12.xx range?
So I guess from what I know, why would one use both in a system? Is one better than the other? I have run a calcium reactor but never a stirrer.
Sorry if this is in the wrong forum! (could a mod please move to the correct forum if not?)
