Since we stop here on the discussion of Chloramine level in Singapore ... let's summarize the points ...

1. Singapore water does have Chloramine.
2. Neutralising Chloramine is not a rocket science. There are several means to do so and easily available in the lfs.
3. Look at the commercial product labels which does neutralise Chloramine and Chlorine. Some products might not neutralise the resultant ammonia during the chemical reaction. Most of the branded commercial products are able to perform the necessary neutralisation. Only a small handful of cheaper products do not.
4. As long as one has a good running cycled filter working, ammonia produced by the general dechlorination will not have adverse reaction to the living organisms.
5. Commercial products are not costly at all compare to the cost of the fish. Don't be stingy on it.
6. Water tests may be conducted but it is up to the individual.
7. Even local water is meant for human consumption, it may be toxic to the fish. Do not go out there to buy cheap offer products immediately. Read thru the discussion and understand it thoroughly.

Most importantly, I must stress, arm yourself with knowledge, not cheaper offer products. If you do not understand the product, test it or ask for detail explaination from the seller or manufacturer.

A very good summary, Matrix.No heavy stuff,easily digested and straight to the point.

My only regret is that we do not have anyone from PUB participating in this thread.Their input would have been very valuable.Anyone here with links to the PUB?

Great summary. Appreciated the simplicity. It suits people like me who cannot handle science and maths.

Q : I was told Chloramine, unlike Chorine, cannot be removed by ageing water over night. It can only be neutralised by introducing anti Cholramine. In this case, what benefits are there to still age our water?

Hi 9 ranchus
First, to use aged water is to dissipate all chlorine and not chloramines in a relative short period for those that don’t use sodium thiosulphate (hypo) for neutralizing the Chlorine.As for the residual NH3 dissociates from Chloramine,as being discussed its value are negligible, easily coped with by your biofilter or any propriety products if you are not comfortable with its presence.It is the Chlorine from the tap that does the “most” damage rather than the ammonia so neutralizing it sets precedence!So if you are still confuse please buy the 2 in 1 preparation for ease of execution.(cp has provided a link on this already)

Hi, Goldrush.
Thanks. In short, there is no purpose to age water if Chlorine is not present in our water - right? There are some hear say about PUB no longer uses Chlorine (Chloramine only) in our water.

The only benefits is temperature and possible containing more oxygen when you change water.

on the latter, based on my testing I stay on the 11th flr and my supply comes from the tank above. O2 from the tap is acceptable not the best measured in the late morning at about 26 degrees. O2 depends on your temperature, so when you age water you have to reduce the temperature to get to the level you want. The easier way is to add 1ml of h2o2 to every 50L, that works. But once you change water that will go very fast. Goldrush review about oxypur rocks, and it last a lot longer.

For info, PUB in the past was using Cl only to treat our water. Since 10 years ago, PUB has been using Cl and ammonia for the treatment and this is why there is residual Cl and Chloramine (due to the binding of NH4 and Cl). No change.

Who ever said PUB don't use Chlorine anymore, he better come out with an explaination.

Chloramine = NH3 + CL2 ... the simplest form of chemistry. Chloramine formation is by adding ammonia compound ( in term of gas or solid salt ) into chlorinated water. And the reaction produce the product that we now talking about. I not going into detail of the chemical reaction formulation. Too complex for many.


Chlorine(aq) form can be easily dissipated thru heavy agitation in a containment area, but chloramine(aq) is very stable disinfectant. By right, Chloramine should still be able to dissipated, but the duration can last for months. Aging water in the good old days will not work as good as today. What I meant is that there are always some form of free chlorine in our water, so aging and agitating the water will still work on these minute trace of free chlorine.
