RO Water

[schwastika]

Greetings bros, i'm setting up a 4 feet aquarium and im wondering if its necessary to use RO treated water for my saltwater mixture.

Most people use deionised water or distilled water. RO water is an overkill if you were to get an RO unit. The thing about avoiding tapwater is that it might have certain chemicals which you might want to avoid like heavy metals, silicates, etc. Heavy metals can be toxic to sensitive invertebrates and silicates usually cause diatom bloom. This makes your tank glass brown very fast.

If you can live with diatoms and don't keep sensitive invertebrates by all means just stick to tapwater. I use tapwater all along. Then again different parts of Singapore will have different tapwater properties.

Oh....but how do i get get ionised or distilled water?...is there some kind of systems or ways to get distilled water instead of actually buying it?...i'm just thinking of alternative ways to save cost.

Deionised unit can be purchased from shops such as:

Distilled water the only convenient way is to buy and have the water company to deliver it to you. Too time consuming to distill it yourself.

You can also buy bottled distilled water from supermarkets, but its a more expensive option. A 1L bottle is around $0.50-$0.65 depending on how cheap you can buy it.
