    Hi all

    How long can you store RO water and, also, how long can you store RO/Salt Mix water?

    I am trying to plan for setting up my new tank but dont want to make RO or salt water now if I cant store it for too long.

    Thanks

    i have kept water for about 1 week in a dark cold room.
    if you have non-see thru vats i am sure a little longer, but then you must aerate the water for 24 hrs before use.
    i would store RO, then mix the salt a day or 2 before, then aerate

    I keep r.o and salt water in 600l drums and it last a long time.
    I have a pump in the sw drum to circulate the water now and again

    nope, remember to check for evaporation. Your salinity will slowly increase, especially if the drum can "breath"

    Salt mix can be kept for a couple of weeks. all that is needed is a small pump to keep things moving. You cannot keep NSW for a number of days, as you will get die off due to temperature changes etc...
    Same applies to having a mix of old tank water and freshly mixed salt. The old water will have bacteria in it that will die off.

    RO cannot be kept for too long either. RO water easily absorbs anything in the air. A closed drum is better. Take a glass of RO water and leave it a couple of days open in your fridge. You can taste the milk, cheese and any other strongly flavoured items in your fridge.
