Yeah you guys are all on the right track. I know it really requires two polls that are linked. One, how many hours per week. and Two, how big is the tank. Me thinks Krish already said it best as it depends also on the automation of your system, especially when you start going above 50 to 75 gallons as the evap amounts, water changes, etc get to be a pain in the arse if you haven't automated. But that being said, I still appreciate the responses so far explaining how big and your what is taking your time. I found out a long time ago that I spent a lot of time diddling around thinking it would help the tank. Now I have automated the mundane things and observe, test when it seems something is changed, and spend the rest of the time researching on why something died. I don't know if people are as anal as I am but I research and read a whole bunch but I can't say I have put that into the equation for the poll. Let's let it roll for now.
