I dont have experience with that diffusor, they look really well made though. Im sure someone can chime in... I actually dont mind the look of the glass diffusors myself.
I see why you have that intake. I have sakura grade cherries also, but I don't have anything on my intake at the moment. was looking to get one of those as well. I probably will at some point. right now i don't have many tiny babies and none of my shrimps are berried so I'm hoping its ok for now.
