Chloroamine's concern - PUB reply

[jhseah]

Hi to all

I'm concerned about the level of chloroamine in our potable water so I post my queries to the PUB.

Below is their reply:

"The chloramine level in our potable water is safe for consumption.

Chloramines are harmful only when they go directly into the blood stream. Our digestive process neutralises the chloramines before they reach the blood stream. However, fish take chloramines directly into their blood stream through the grills. Hence chloramines must be removed from water for fishkeeping."

Think we got no choice but to use anti-chloroamine solution.

Using aged water is not a fool-proof method as chloroamine takes around 2wks (read from somewhere) to dissapate unlike chlorine which takes only a few days.

Just a note... many anti-chlorine solutions will handle chloramine, usually at double dose. Check the labels on your anti-chlorines.

Hi Vinz, does this mean that all the tap water in Singapore has Chloramine? Should we always use anti-chlorine for water changes?

I think you can safely assume most if not all tap water in Singapore has chloramine.

Err... to use or not is up to you. Chloramine does not dissapate easily and while our fishes don't seem stressed, I wonder how much damage they may have taken. I'm still deciding, but I'm likely to start using anti-chlorine again.
