Does this look right?

Its been 15 years since I had a fish tank and its time to get back into it. My work causes me to travel every couple weeks so my goal is to design a system with Apex that will be able to hold up when I'm not around. Does the diagram I made look right?

My plan is to keep the back up return pump isolated and not in use unless I am away on travel. When I do leave I would open the T handles and then if something happened to my primary I could remotely turn on the back up. Would that work?

Looks great! You got an auto water change setup going it looks like? A couple things I would add on is to add a gate valve on the main drain line to fine tune flow through the system. And I can’t tell if you have an ATO set up or not. With your setup it looks like you could have a pump on your massive RO storage and hook up a solenoid and float valve into the sump

JosephM thanks! I didnt even think about adjusting the return flow, a gate valve will definitely be added.

My plan is to have a solenoid set up to auto top off my RO tank and then use a dosing pump for the ATO and water change.
