Seriously considering AWC systems for my two tanks on the first floor with basement mixing station and rodi brute.
Any one know of a tutorial or can give a brief explanation? How not to activate the ATO when changing water is a concern I can't figure out on my own. I'm somewhat familiar without Mobius and assume (?) I can calibrate the pumps using the app and assume (?) I can program x amount out and x amount back in on timers through Mobius but how do I stop the ATO from activating. I have no Apex or other controllers so the AWC will have to be done with a stand alone system or app controlled.
 
Mobius has templates built into the versa pumps. You simply would have one versa pulling water from your sump or display and sending the output to your drain and then a second versa pulling new saltwater and dumping it back into your sump. Set them both for the same amount you want to change daily and then set your timer. by default, I think it’s set to run continuously throughout the day, but you can schedule it to run as short or as long as you want.

1-2% daily is a good amount to set up for AWC. If you are taking out and adding in at the same time it should not trigger your ato.

I'm thinking drain from the last chamber and fill in the first. This may not be as complicated as I thought. Thanks for your help.
 
Update I think I'm making progress and have a 2 hour cycle running on two pumps. I think my problem is the UI is a bit different because the videos are early and it looks different and I'm also a bit tech challenged and it takes a while to learn new stuff.
I forgot to mention I scored a 4 pack with base station NOS and my LFS for $600. I was only planning in a AWC but now calcium ans alk are going on dosers also. These versa are really quite compared to my reefdose.

Bumping this because I'm lost. I have Android and iPhone and both do not have the icons at the bottom so I can not select the pumps to complete the setup . I'm using two videos and both appear the same but I am unable to complete the process.
Anyone have any suggestions?

And this is what the videos show when they instruct to select the pump icon

HOW MUCH DOES A FISH’S FEEDING REQUIREMENTS AFFECT YOUR STOCKING DECISIONS?
