I just got my bio-fluval startum off amazon and I washed it as the bag said too, but when I look at other places, it said that you shouldn’t. Did I do something wrong? Can I still use it?

Hi, I’m a beginner at fish keeping and I have a lidded tank because I have a cat. I’ve been seeing recommendations to get floater plants, but I’m unsure if it’s needed or if they would grow because of the lid. What should I do?
