If I'm really in a rush I'll use aquarium water conditioner to de-chlorinate. Rupertofoz, what is your opinion of those de-chlorinating conditioners?
Add 100 L of this, and assuming all of the Chloramine is broken down by your Ammo Lock, you have just added 1.8 mg/L *100 L = 180 mg of ammonia in your system.
Now you have 180 mg of ammonia in 1000 L of water, which is only .18 mg/L of ammonia once it is diluted.
Is this correct?
How do you calculate TAN from concentrations of NH3 and NH4+? Correct me if I am wrong, but this is how I would do it...
[(mg/L of NH3) + (mg/L of NH4)] / (14 mg/mole of N) = Total Ammonia as Nitrogen
It has been a while since I have done this caculation.
RupertofOz- how do you use the oft posted table?
I haven't totally read this page yet, but I think it is a good way to learn about ammonia.
Chlorinated water is usable in small amounts, if you have to use it...
Luckily, chlorine can be dissipated from water by exposure to sunlight and aeration. Adding a "bubbler" to a container of water for 24 hours is usually enough to make it safe.
The problem with tap water, is that some water suppliers dose with "chloramine" rather than chlorine...
Chloramine, while it does eventually breakdown through exposure to sunlight (UV), can't be dissipated by bubbling as chlorinated water can be...
And by the very nature of the compound, breaks down into ammonia or ammonium.... depending on pH...with possible fatal consequences to fish... or at the very least to an elevated "ammonia" spike in your system...
Indeed Chloramines can pose a risk for both human hemodialysis patients as well as fish. Chloramines easily enter the bloodstream through dialysis membranes and the gills of fish.
The most effective nonchemical method for removing chloramines is by activated carbon and certain spectrum UV wavelengths can also breakdown chloramine...
Activated carbon does not adsorb chloramines but rather removes them through its ability to act as a catalyst for the chemical breakdown of chloramines to innocuous chlorides in water.
This catalytic reaction involves the formation of a carbon oxide intermediate (CO*). This reaction is as follows:
NH2Cl + H2O + C* = NH3 + Cl- + H+ + CO*
David, never a problem mentioning other forums. We are all in this together!
