Hi All - I recently made up a batch of all in one and I managed to get the local fish shop to give me a litre of RO water. My tap water is extremely hard so can't use that. All anyone sells is DI water (supermarkets, car shops etc.) for use with car batteries or for ironing. Can I use that instead of tap water? I can get distilled online but I'd rather buy from a shop if possible.
Thanks!
Thanks!
