Possibly too many fish for the moment, but worry not, all can be kept in check with testing and water changes if you are on the job and willing to put in the time. I wouldn't put any more though. It really would be best to let it settle a while.
You may get a cloudy bloom, but that's not necessarily a bad thing. It means the bacterial population is increasing. It's still early days for the tank yet since you are starting from scratch...
My last 220lt took a couple of weeks to stabilize (more or less) and that was with media from other filters and all the substrate from a 2 footer... And it still has a ways to go.
