Apex has everything you need and very flexible. Fusion is a good app for your phone, it becomes a remote control for all your pumps, Co2, dosing pumps, dimm lights, and variable speed Vortech (assuming you have those features in those things, the Apex can control it). Apex also has a huge user based forum where you can ask questions and get good answers.
I used my apex with 3 float switches, a sump-drain pump, carbon block and a solenoid to create an auto water change system, changes 20% a day just before the Co2 comes on, eliminated most algae.
