10g or 20g?

[ReefEze]

Hi,

I was wondering if i should purchase a 20g tank, or use a 10g of mine. I was thinking of useing this for macroalgea cultivation also, and possibly a lionfish later...

TIA

A ten gallon is plenty sufficient,I don't think you can keep the lionfish with it.Try a blue damsel.
