Thanks for all the compliments
I have yet to properly label the two buttons (doorbells) that is why I just have tape beside one but they are for feeding cycles. I have them attached to the apex to trigger a set of actions. One turns off the return and my mp10 for 10 mins which allows me to feed my clown fish etc. The other button triggers a cycle for feeding the coral. It turns off return and sets mp10 to a slower flow rate for 30mins as well as shutting off my skimmer for an additional 30mins after the return and mp10 resume.
