So, I purchased a Hydor Inline Heater, and I'm almost finished with my inline C02 diffuser. My plan was to put the C02 on the filter out, and the heater on the filter in. Now because if space, I'm looking at putting them both on the filter output. Does this sound like a bad idea to anyone?

Also, I don't want to have to order bio balls online since my LFS doesn't carry them (lame, right?), so can I use chopped up rings of PVC pipe to fill my diffusor with to increase the "dwell time" of the bubbles?
