I haven't used that exact one but Sicce is a decent make. I had a different Syncra pump (one of the nano ones) and it was perfectly fine. I'd say it's about as good as Eheim or Tunze.
I guess 5000 L/H is probably about right for your tank? At 1.5 m head it will probably give 3500L/h or so, which is about 10x turnover.
