What are some of the modifications that you guys have done to make your Aquapod better?

I run a sapphire aquatics skimmer and just recently put in a 660GPH Rio Hyperflow 10 Pump that fits perfectly in the back. Highly recomend this pump. Has anyone tried flex piping on the manufacturers return instead of the flimsy plastic deflector?

Curious of a small florescent fixture so I can run my MH for less hours and still have viewing time. Anyone seen a small fixture that could fit easily behind the MH fixture?
