From my experiance, the idea V\'s the practicality is a major issue. I have never stored RO water for consumption for any length of time, so I don\'t know what the helth risks are. Who knows what might enter the water if it\'s left long enough. I use food grade tubs with snap fit tops to store my sea water, not sure I would store drinking water in them tho, pop bottles is what I use for that, as I use ro in my SodaStream.
When I asked about ro for fresh water trops, the Aquatic centre said unless your going to match the exact water conditions for the fish it\'s a bad idea, as all the buffering compounds are missing, that will give rise to acidic water. They also said that the majority of buffering agents and additives are formulated with tap water in mind, that said so are some of the synthetic salts for marine, only a few are formulated for RO.
I have done and used both and can report that my FW trops survied ok, and whilst the sea water was lacking a little it was still ok. So if you can stand the long filter times you should be good to go.
I won\'t be storing it for any length of time, just for a day or two i.e. fire the filter up over night and then use the RO within a day or so.
I appreciate that it will take too long for an "on demand" thing, but so I can basically use it like that, or close too.
As for the fish, it would be used with the appropriate minerals, but as every other water change - so it would minimise the amount of phosphates etc that seem to appear at this time of year.
Plus it also means that I can use it for wash and other wine/mead batches. I keep an eye on the pH levels of the wine/mead batches anyway, because, particularly meads, they can show funny pH results because of the gluconic acid levels fluctuating during the ferment, so it will probably ferment fine without any acid additions up front and I can just add a bit for taste after the ferment has finished.....
Or at least that\'s the basic plan......
Sorry if I have waffled on but I am posting on an iPhone and it\'s not easy to see or edit what you have typed.
Yup! know where you\'re comin\' from there, I have a G1/"googlephone" and that can also be a bit of a PITA when inputting longer sections of text...
