I am trying to automate my saltwater changes a little more, not full auto but eliminate buckets. What is the best way to put mixed salt water back into your display? I am pumping from my salt water tank in the basement and bought a big enough pump to handle that. I was thinking 1" pvc for most of the run and then 1" flex (through the floor) to the display. How would I finish that part of it? I was thinking a ball valve and then what? thanks!
