Hi everyone, I'm just getting ready to buy my first Apex for my 150 and 50 gallon reef tanks. They are two completely separate systems the 150 is in the wall downstairs and the 50 is in the our living on the main floor.
I'm going to have a DOS for each that will be running a continuous water change on each system. I intend to have a solenoid set up with high and low float switches on BOB's for auto filling the ATO containers. Will also be connecting a float switch in the sumps to each BOB to shut off the skimmer when I forget to kill them before turning off my return pump (seems I manage to have this brain-fart every few months).
In order to monitor PH, Temp, Conductivity, and ORP on the second tank with PM1 and PM2 modules and probes the cost is about the same or even a bit more than using 2 Apex units. I could live without ORP monitoring on the second tank which would make the single Apex option cheaper but not a huge difference.
My question is should I go with 2 separate Apex units or run both from one head unit? Which way would be better in the long run? How would each option work with Fusion?
Thanks in advance.
