The majority of my tank is automated. Top offs and water changes are manual for me though. My tank is too big(300g DD) and my property not conducive to setting up large ATO and water change station. I just roll some brute trash cans out. As for me it isnt a question of not wanting to get my arms wet but rather I just cant reach everything. But I check my tanks vitals every other day and spend atleast 1 hour each day observing and appreciating it.
