Ro Water ?

[Happy Harry]

Hi all...Now as some of you may know I have got an orca 550 tl in the making...And I would like to know how long does RO water last in a sealed container without being mixed with salt??? I have a 50 gallon ro system and do 10%ish water changes a week,and as you have to bin the 1st 25 lts, And it seems a bit of a waste, i just wonderd if you can run off say 100lts and store it ...And use it when needed...... Cheers HH

In a sealed container it will be fine for ages (mine is typically stored for a couple of weeks at the moment).

You dont have to run off 25ltrs every time you make RO water (at least I dont do it). I have an inline TDS meter on mine so I run off maybe half a litre and watch the output TDS, once thats zero I use the rest of the water after that.
