Mixing saltwater

[gavinsepanik]

SO since setting up my first nano, a 10 gallon fusion, a couple of months ago I have been doing 1 gal water changes weekly or sometimes bi-weekly. I was wondering If I could premix my IO mix in 1 gallon jugs (sealed) and store for multiple weeks until using. Is this a possibility? Will calcium, alk, mag, and salinity fluctuate when stored for multiple weeks at a time? Thanks for your time!

With the size of your WC I would personally just by premixed from my LFS. IO will be fine in a sealed bucket. Just drop a pump in overnight to aerate the water and test the water. You can supplement the Ca, Mg, Alk if need be.

Just get an empty 5g Absopure bottle with a lid off Craigslist and fill it once a month
