I find it funny when anyone bashes automation in the hobby if any part of their system is plugged into an outlet. I know
@exnisstech retracted the initial bash, but some folks haven't seen your point. Frankly, we easily forget that an essential device like our return pump is automated, our wavemakers are automation. Unless your out here scooping buckets back and forth between your sump and display you've got a minimal degree of automation.
It's also worth continuing with the discussion that not everyone is fully invested in aquariums as a hobby. I enjoying doing all kinds of tinkering in my tank, but it's also not only "my" tank; the fiancé loves the tank even more than me while I do 90% of the work. We're not going to be able to go on any overnight dive trip if not for sufficient automation that enables a non-hobbyist or enthusiastic neighbor to "babysit" our tank. Having a service that comes once a month to do a major water change also helps when some of us don't have the time or personal resources we'd like to dedicate to a hobby. If you've got room (and support) for a tank but not the space (or permission) for storing larger quantities of water needed for larger water changes, having that major water change done by someone else once a month doesn't make you any less of a hobbyists. I'm glad most folks in the thread seem to agree with that idea.
I think the time and stability points are clear arguments in favor of automation. As a public school teacher, who also sponsors extra curricular activities, I lose out an a lot of afternoons and even weekends where I don't have time to also take full responsibility for the tank. Priorities are always being balanced and when technological advances allow us to reduce the burden of deciding between responsibilities/interests we can carry more or our cares/priorities without totally giving things up.
I'm loving this discussion, but I also think it's important we avoid any dichotomy where automation means lazy or assistance with regular/major service is an affront to hobbyists. I rather give a shout out to any tank service workers who read this thread. You bring mini ocean museums into peoples homes, and that's pretty awesome!
