Hello reefers just got my new apex controller in last week I put everything together how it explains .I have to say not easy there's is a lot of things you have to do to get it running right but one's you do man this thing is awesome you could basically control everything you plug in to the modules from your computer or your phone.So far I have my ATI lights my return pumps my skimmer ,circulating pumps,heater,and sump light so far everything is running smoothly.
