Ok so I have my containers 2 60 gallon upright ones. I was thinking of plumbing these with a T in the RODI line and a float switch in each container. Thought having the float lower in the salt would be my best option to keep salt out of the fresh water. Would this be a good approach or am I thinking wrong? This will be an auto water change setup and I plan to fill the ATO container with a pump also.
I will post up a pic, waiting on the bulkhead fittings now for tanks so they aren't installed yet.
