What would you do?

Fuge. One or two 4' GE Ultra Daylights would be all you'd need. They run about $4 at Canadian Tire. Set it up to be slightly elevated behind your main system. Fed with a maxijet from your main tank. Drill a hole for a 1" drain just below the lip of the tank on one face. Have this return back to your main system.

Toss Calerupa in it a good sand bed and critters and you are set.
