Re: distilled water?
I use a mix of de-ionized and distilled depending on what is available cheaply, I pay about $8 Australian per 20 litres for bulk distilled delivered. Truck turns up and re-fills my 4 20L cubes. If I'm out of distilled and desperate I get de-ionized from the local hardware store at about $1 per litre. It is fine to use de-ionized, just dont use de-mineralised.
Cheers
