no, no sump, it has hang on skimmer but it does have an in tank fuge, full of cheato
With 180 Gal you may want to consider a much larger skimmer then HOB espesially for a reef tank you want something rated at least double you tank size with at least 600 l/h air intake the more the better.
So looks like you need a sump, you can hide all equipment there: skimmer, heater, refugium, carbon.
