Pre-mix sea salt water for water change ~ ok?

[poh34]

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?

Will the mineral in the water "die" off after time and cause my weekly water change to be useless/ineffective?

Thanks.

Bro Poh,

You need to at least circulate your pre-mixed sea water, using a small pump will be sufficient. Aeration will be an added advantage. You may use a timer control to turn on/off your circulating pump and air-pump in a 1 hrs on follow by 1 hours off pattern.

I dont think there will be any loss of traced element while storing in the container, iodine being exception.

Hope my view point helps.

Cheers

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.

Aeration is to bring the pH down to normal values. Newly mixed seawater without aeration mixes to a pH of above 9.

Thanks for all e advises.

Now i change method for testing.

Keep tap water for 3 days then mixed with sea salt during weekly change.

Cos my tank water pH around 7 and got no air pump.

Try this method see whether pH will be higher a not.
