I'm wondering what others use as RODI water?

I'm not going to use NSW and will get a RO/DI unit in the coming months, in the meantime I'm using Pure Dew bottled water. 

There are some other products out there in larger bottles (Pure Dew is 10L max). Does anyone use anything else? I've got fish only for now, won't go coral until I have RO/DI unit.

I used Pure Dew when first starting out then had a RO/DI Unit custom designed and made in china via Aliexpress. Worked out a bit dearer than off the shelf units here in NZ but is a far superior system. 

One thing that seems to be common throughout NZ is high silicates within our water - this is also true for Pure Dew. Silicates can fuel algae growth and can be a big issue for many without realising it. While an RO/DI Unit helps with this Silicates can get through a membrane and the TDS of the water will still read zero as silicate is not conductive. 

Having a couple stages on the DI can help reduce this a bit. 

Cheers, where did you buy Pure Dew? Pak n Save is about $5.50 while Countdown is about $6.50 - just making sure this is about right?

 

 

Yea sounds about right - I was getting it from Countdown and from memory it was around $6-7
