Modding Filter For Betta

How To: Setup Azoo Palm Filter - YouTube

I'm thinking of modding the 150 model like this one in the video.

What are the benefits of doing this and will it slow down the current enough that my betta won't be jumbled all around?

Actually, my plan was to copy this setup with those two modded filters. Does this sound like a good idea?
