Question for ya's,

Decided to use the available space behind my 2.5 to install a sump - maybe a refugium if I can come up with a neat way to light it (thinking LEDs would be appropriate in this case).

Due to temperature issues already - I'm thinking I don't want to add another pump to the system. Best alternative I could come up with was to run a syphon fill, then an air driven lift tube to return water to the main tank.

I've got a mockup on the desk working right now - so I know the system COULD work - and it's dropped the tank temperatures from 81F to 77 (I'm guessing the air lift is working somewhat like an evaporative cooler)

I'm wondering if I've missed something in my plan to do this - is there a good reason why I Shouldn't do it? Noise and saltcreep were the only downsides I can see to the system...
