As long as a conditioner removes chlorine, chloramine, and ammonia, it's fine. Personally, I prefer that it does nothing else.
For example, I question whether my fish really need an ingredient that "enhances slime coat". But I know that if I ever need to use Purigen, it will coat that too; rendering it useless.
And Amquel Plus eliminates nitrates. My plants want those nitrates!
Those two I know about. No telling what other unintended side effects optional ingredients might have. Better to keep it simple and single-purpose.
Several will fit that bill, but since acquiring some Purigen for emergency use, I now use only Prime; since I know for certain it's compatible.
