i do think auto is better and worse I used to dose manually and fill manually and i suspect that there were swings but maybe those swings strengthen your livestock. with auto you can leave a while and not worry and with a controller at least you can look in on things while away. I wouldn't need anyone to look at the tank while I am away but it would make me feel better. I am almost completely automated. I not convinced that this is good but it is easier. I still test and look over everything every day, but it is nice not having your hands in the tank every day out of necessity
