Salt mixing circulation question?

[Dundermifflin]

If I'm using two 55 gallon barrels where the tops are sealed how do I circulate the water in the salt mixing barrel once it's mixed and prior to going in the tank since I can't get a powerhead inside the barrel.

Plan to have RO/DI on top and the Salt mixing on the bottom. Top will gravity feed into salt mixing barrel. Will mix the salt using an external Pan World pump. My question is once mixed how long can the saltwater be stored before going into the main tank and how do I circulate it with these types of barrels after the mixing is complete? Also, I assume I can use the same Pan World pump to pump the water 30 feet (level) into the sump, correct? How do I plumb it to serve both purposes?

Take a look at this thread

Theres plenty of info and pictures to look at how there plumbed. Really all you need is a few valves and some pvc to make it work. As for how to get it to the display tank. You will need to determine if the paticular pump you have can pump that amount of distance. Theres not enough info thats posted to determine whether that paticular pump can support that amount distance. If I remember correctly alot of guys that have to pump over 20ft use reeflo pumps such as the dart. I could be wrong but dig through that thread there tons of info and pic.
