THE SIPHON BREAK To prevent a Massive New Salt Water Dump)
One more important part of the design.
I may not need this, but I won't know till I test things.
My sump is low to the ground. And the Pump is not Peristaltic. It's just a Maxi-Jet 1200. (So open flow)
If the Water in the Reservoir is higher, then sump reservoir section during a fill, a siphon could drain more than I wish (From the New Water Reservoir).
This minor adjustment (Siphon break) may be needed. More ways than one to do this.
