I'm planning out a 90Gallon setup and was looking at the Apex Jr as a controller, the main reason being the cost factor at the startup. Is the Apex Jr upgradable later-on up to the level of an A3 or will there be anything missing permanently (Other than the ethernet). In future I will probably run a couple of DOS, possibly 2 E8 power bars and when the growth hits a specific level, a Trident. Lights and pumps will be AI so there will be a need for an MXM module as well. Other than that I don't think I will need Flow monitoring, Ozone etc.
Will the Apex Jr be sufficient of should I wait and get the A3 right away.
