Boy I hope one day to have the slightest clue what all that calcium reactor jibber-jabber talk means...
Then I hope to have one of those wonderful units attached to my tank! LOL
Ahh, one can only dream!
On a serious note, how plausible would it be to put a CA reactor on a tank like mine with no sump? Wouldn't the effluent be harmful to my tank inhabitants having such a high Alk and low pH, or is the flow so low (aka like dripping Kalk) that it wouldn't be dangerous?
