Imo, it's the least complicated commercial carbon dosing system and also the least expensive.
From the limited exposure I have had it's not what you want to use to knock down out of control high levels of nutrients. It does do a very good job of keeping a balance once the system is in a standard target range.
It's way too potent to put on a dosing system.........you have to hand dose. A small amount of this goes a long way.
Here's more info.......you can put in your systems volume in the calculater and you'll see what I mean by how little you need
