Rena????aren't they the ones who make the heater mount on the intake? If so, will you be doing this too? I always thought it was pretty cool to have the heater on the intake like that.
Oh, as far as media........IDK. I don't run a canister. Do you have any problems with your tank now? If so, I would say to run the media that will help you out. Like a nitrate absorbing media, ect.
