I did end up adding my Sicce pump for the WB peninsula 15. I can't remember if it's a 1.0 or 1.5, but it is nice and quiet. I removed one of the plastic shrouds and put it in at a bit of an angle. Works.
The stock waterbox pump sounded like there were rocks in the impeller from day one. They should be ashamed to ship such a low quality product with such an expensive tank.
