There’s nothing specific that comes to mind about automation - my primary concern is monitoring for changes to the tank and water parameters. The most tempting part of the apex for me is the trident unit, but the reviews are all over the map on this. I do have a pretty complete arsenal of Hanna test units but it would be nice to have life simplified a bit. Lol Are you using the hydros to monitor parameters too?I have the Hydros system. So far I have not run into any limitations. I am slowly converting my system from the DA Archon to the Hydros. I started in the garage. I have it doing ATO, auto water changes, refills DI strage tank, refills fresh salt water tank from mix tank if mix tank is ready to go and refills mix tank with DI when it becomes empty. All I have to do is add the salt mix to the mix tank once it is refilled and press a button when the mix tank is ready. It also controls my return pump, skimmer, heaters and tank cooling. The only thing I have left to switch over is the lighting and leak detection. I am doing it slowly. I have a Control 4 and 2 Control 2's in the garage. I have to Control XS units at the tank. I also have 4 of the WiFi power strips. Is there something specific you want to do with one that you are concerned about.
