I have a biowheel 200 on my 29, gallon it works well, I would rather have a sump though. My biowheel has a "sweet spot" for the water level, too high and it splashes all over my light, too low and there are a ton of microbubbles, just right and it works great. As for the skimmer, on a tank that small you can get away without one, just keep up with weekly partial water changes, don't overfeed and test your water weekly. My skimmer has been broken for some time and my levels are fine. I also do have corals so you should not have a problem with fowlr
Welcome to AA and good luck with your new tank.
