Hey Scott
I think it's probably okay too mix them in the reactor I know that some people run them both together in canister filters. The carbon will probably lose its effectiveness before the Phosar though.

What kind of noise is it making? I don't really hear mine but I have alot of other noise in the fish room.

The only thing I can think of that might be bad about shutting it off at night is if it's supporting bacteria kinda like a fluidized bed it might die off causing an ammonia spike.

One other thing with the Maxijet from my CA reactor manual is that your supposed to have a pressure relief hole to keep from ruining the pump. I used to just put a hole in the output line under water close to the pump.
