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.
