Fuge Q's

[Myka]

It depends what you want the fuge for. If you want it for nutrient export, then it can be hooked inline with your sump. If you want it for pod growth, then HOB or gravity fed is better. Size and what you put in it also depends what you want it for. For nutrient export, I would suggest at least 10% of the system's volume, but for pods you can get away with a gallon or two (or more if wanted), and the inhabitants will vary.

I had a gravity return fuge on my last tank. It was impossible to get it to stop making bubbles when it fed back into the tank, which made a mess of my lights when they popped. My fuge now is just a divider in the sump.
