Here are two 55 gallon drums. The one on the left is for RODI water and the one on the right is for fresh saltwater. I have a pump in the RODI drum that pumps water to the other drum where I mix up the salt. I also use these drums to change water out for my established 187 gallon tank. Auto top-off for both the new peninsula tank and the 187 gallon tank are drawn from the RODI drum.
I also added some valves to the right of the drum used to mix up new saltwater (there is a pump inside this drum as well). So if I want to pump water back into the peninsula tank I leave the valves as is. If I want it to go to the 187 gallon tank I turn each one the other way.
This is the plumbing I put in to return water from the saltwater drum to the Dreambox for the peninsula tank. And here is the last part of it that goes into the Dreambox.
