I have lost an entire tank of plants to a 20% chloramine-laced tap water
change a few yeas ago (It was a straight addition, however). At the time I
had no idea chloramine would actually damage plants. Nowadays, I use an
inexpensive Kleen-plus CTR-210 countertop water filter with an ordinary
carbon filter and I avoid chloramine and chemical dechlorinators altogether.
Before I put this liquid menace in my tanks in ANY amount I am surely not
alone in needing some specific values for time, concentration and volume
before taking such a chance. Is it safe for example, to assume all
municipalities add chloramine in identical concentrations? Perhaps it is.
But if not, is it possible that the initial concentration may affect the
length of time neaded for this Rxn to eliminate chloramine? What about the
initial volume of tap water that should be stored? Is its volume also to be
I think a formula would clarify the questions. Something like; INITIAL
CONC. CHLORAMINE (Xmg/L) over some TIME(X days) will yield ----> FINAL
CONC. CHLORAMINE (Zero mg/L) at TIME (Zero days).
