AWC on 2 systems, with only 3 Dos heads

[dhof]

I recently setup a frag tank, and decided to dump the AWC wastewater from my DT into the Frag Tank. Then, with only 1 more Dos head, I'm able to AWC the Frag tank out to the Basement Sump.

Concept is: The 'dirty' display tank water is 'clean enough' for the frag tank perspective. Might even be beneficial in that it brings Nitrates and Phosphates from the DT over as well.

Anyway, not sure I've seen the concept posted here very much so figured I'd share. Here's a graphic if it is easier to understand.

I do something similar in this thread with my QT:

Makes sense. I use ‘old’ AWC water to bring the salinity up in my QT.
