Sure. It, and products like it such as Salifert all in one, have pros and cons relative to two part systems.

The main pro is convenience.

The main cons are a slight pH reducing effect (likely too small to easily see), cost, and complications when trying to use it in a system with automated testing and dosing system.

Like a two part that contains extra trace elements, the amount they add is tied to the calcification rate and thus cannot be adjusted separately in a way that might be more suited to your systems needs.
