Remote tank using a dos to do "water changes"

[WDKegge]

Have a question hoping maybe someone can answer.

I am currently in the works of building a remote mangrove tank for my office.

The tank is a waterbox 40 Frag system, the goal is to do a "water change" if you will with my main display tank (200ish gallon system) slowly over the course of the day. The plan is to use a Neptune DOS to change water from the display to the frag system. The tanks are roughly 15 feet apart. for backup and safety I am going to use a Neptune FMM and a optical water level sensor on both sumps to notify me if anything were to fail.

Has anyone done something similar to this? Anything else I should worry about?

Why not just use fresh salt water since then youll need another dos to replenish the display.

Correct me if I am wrong but would a dos not be able to swap water from two sources, the whole idea is to swap water between displays.
