Dear All,
I had a basic question as i can't find a definite answer from the internet.
My current method for water change :
I pre-mix the sea salt into water and stored in 2 large water bag (without aeration).
This is to save time/trouble for my weekly water change as 2 bag can last me one month plus.
Which is to say, i only need to mix sea salt with water monthly.
I would like to check whether this current method is ok? Yes it is possible, use a small pump to circulate the water. if not, i think its will be fine since its "sterile" unlike NSW. just stir the water abit before water change.
Will the mineral in the water "die" off after time and cause my weekly water change to be useless/ineffective? no it wont. it is ok, or perhaps like what cedric suggested, iodine might go away so dose it to supplement it after you do your waterchange. i'm currently going to set up my auto water change system, will leave the premixed water in a big pail too. i dun see any problem being like this.
