Keeping Premixed Saltwater in Barrel

[CCK_8814]

Another question, those of you doing AWC, are you using an Apex DOS? Or?

I keep 145 gallons of saltwater on hand, I generally use 100 gallons via my AWC with DOS every 60 days, then I make more. I run my mixing station pump for a few hours when I originally make new saltwater (Instant Ocean). Then an airstone with a small airpump is all that I use to keep the saltwater aerated. I’ve never had a problem doing it this way in 2 years. The small 35gallon leg tank to the left and behind the big tank is full of DI water.
