extra sw how long will it last?

[Beemo]

i made too much sw during a water change, i have about 2 gallons of premixed RO water in a bucket.
how long will this sw mix last, its just in a bucket with no water movement or airstone.
should i just flush it? :lol:

2 gallons will get me a 20% water change next time since its just a 10g tank

I would atleast have airstone it or something for water movement. Otherwise it will go stale.

 

[egdevilboy]

keep it moving via a powerhead and possibly covered and you'll be alright

I mix right after a water change so I have some on hand in case of an emergency water change. I keep it for a week in the "brute" trashcan. I keep a mag 3 going and a heater. change every week or so and no problems.
