ATO water

Mine is in an old salt bucket with a sealed top. Just a small hole in the top for the hose
 
I make 2 weeks worth at a time my ato container is a christmas wrapping container holds about 5 gallons of water. This used to be one weeks worth of water until I switched to led's
 
mine will last about a week on a cool days. I only store around 9 gallons. and the sw is filled and then mixed about 1 to 2 days before using.
 
I keep a 40 gallon container filled with my RO/DI water that I use to make salt water and fill up my ATO reservoir. I do not have a circulation pump in my container.
 
opps sorry, No circulation. there is some slight movement of backflow when the pump stops. but not a lot. if you can keep it air tight and no light it will keep for a long time with no circulation. due to nothing in the water
 
i store mine in a 5gal jug in my stand. No circulation and only minimally exposed to air (lid just cracked enough to prevent a vacuum effect when the ATO pump kicks on).
 
I used to store mine in a food grade 55 gallon drum. Hole was only big enough at the top to accept the RO/DI hose. No circulation. My uneducated guess is the only issue with sealed but stagnant RO/DI would be leaching oxygen content...but that should be no big deal right? A few trips through the sump and skimmer fixes that no?
