I wish I could do an auto drip system but since I'm an actual hobbyists I just dont see the point. If I had a fish room it makes sense, but imo most folks just need to stop being lazy and change the water lol. Even on this site only a handful of you seem to have ponds worth of fish where auto drips are feasible... I may be wrong but I enjoy doing maintenance because it alerts me to any change in my tanks
Even a single good-sized tank makes a "drip" system (or at least a plumbed system for draining/refilling, like mine) very worthwhile, IMHO. The larger the tank...and/or the more of them...and/or the older the aquarist

In my case, for example...I am down to a single 20-ish gallon tank that still demands the use of buckets and it's barely tolerable. Gotta link it up to the rest of "the system" before my next birthday...
