I really am not a fan of the power heads at petco/pet smart. Just cheap manufacturing and short shelf life. If you can find used equipment on marketplace it may be a better route.
I have had decent luck with jebao brand wave makers off Amazon if you’re on a budget as some of the household names in reefing can be a bit pricey for people new to the hobby. Again, you can check for used equipment here or on places like Facebook marketplace.
Take your time and don’t rush putting livestock into the tank. It’s advice that’s often ignored by newbies but it’s valuable to wait and do things correctly with proper equipment the first go-around.
