I'm not sure what a 130p is. If it means it is 130mm diameter, and you want a UHC filter for it, I'd recommend either the Kson UHC or Astronomic E UHC filter.
The more typical UHC and Ultrablock filter will work in a 130mm telescope, but the images will be dimmer as they are meant for 8" or larger telescopes.
You'll have fun comparing the views in a UHC to your broadband filter. They are both useful.
