Tap Water

[Aaronb]

Hi guys,

I’m new to Singapore and dying to setup a reef system again. Just wanna find out how is the quality of tapwater? Do i need to buy a ro unit? I live in the east...

Its depends on the location. Anecdoctal hearsay states that Sembawang has the lowest TDS readings and thus the best tap water quality.

However, it is my firm belief that one of the best investments one can make for his or her reef tank is to purchase a quality RO/DI unit or get a supply of distilled water from a drinking water supply company.

Many algae outbreak occurences in reef tanks have their origins in tap water being used.

Having RO is easier for long term setup. An alternative is to have water delivered to your doorstep.(see link below)

Lots of aquarists here relies on RO/DI. My tank is small so I currently use bottled distilled.

Singapore tap water meets and exceeds WHO drinking water guidelines. - http://www.pub.gov.sg/general/Pages/WaterTreatment.aspx

Double digit percentage of what comes out the tap is "reclaimed" water called Newater. *wink wink*

Thanks guys for the help... I have a 350l system so i think its in my best intrest to get an ro/di unit...

For tap water I think it is not only the TDS but also the chlorine that is inside, It is bad for a reef tank. RI/DO do remover chlorine also, so it is good to own one. =)

i also live in the east and just started with this hobby 6 months ago. so far i only use tap water with no problems. probably because i don't have those high tech corals. only have gonio, zoa, gps and mushrooms.
