Salt mixing station

[Lostreef]

Wanting to set up an RODI and salt mixing station. This will be for a 230 gallon (total volume) display tank and a 40 gallon qt tank. Looking for suggestions:
1.) Size of holding tanks?
2.) Where to buy?
3). Any configuration do’s / don’ts / advice?
Thanks

I just built mine. I searched high and low for the best of the best configuration for a mixing station. I have 2 65 gallon tanks in my basement. I ordered them online and got them at tractor supply. See the pics below. I ordered 1 inch pipes. Got the strongest, cheapest pump I could find. I had a few small leaks and have just patched those up. making sure you can pull RODI water, salt water, and pump across both tanks matters. Also I have a hose attached that I pull up to my tank to dispense salt water. I am so happy to get this done.
