God how did we ever keep corals before the trident?
Newbies getting into the hobby that setup a tank with it, will be quitting even sooner when all of a sudden their trident messes up(trust me anything made by humans, will eventually fail), and they have no idea on how to run a simple titration test.
Will it make a difference in your reefkeeping? Only if your lazy and don't like testing. This is not a lazy mans hobby if you want to keep high end corals and fish.
Only thing I see the trident doing is making it easier to perform tests, and you don't have to personally take the time out of your day to do them.
I personally cannot see spending the 1k(need to upgrade my apex also) to find out. My time testing is not worth that much to me.
