salt water life span

[sansouci01]

I'm finally mixing my own salt water with my new ro/di system. I only have a 20 gallon tank so my weekly water changes don't use up much. I would like to make 10 or 15 gallons at a time. How long can you keep salt water? I have an air stone along with a power head and thermometer in my container.

IMO It's better to store RO/DI water You can use it for top offs and it can be mixed to what ever SG you may need. Making up large batches of filtered water makes your RO/DI filter last longer too

Why do you have an airstone?
You need to put a heater in there too.
I only keep my salt to 1 week max. JMO though.
Top off water I keep a little longer.
