I have a 6g nano cube that houses thriving zoas, star polyps, a warty nem, a kenya tree, and a torch. I'm running a crappy DIY turf scrubber in a 1.25g bucket that i plan on converting into a fuge. I have a 30w 6500k CFL light fixture. The tank is 8.5" tall and the clam would be less than 6" from the light, could i keep a 3" crocea or derasa in here provided that i keep up with water changes and supplementation. Also thinking about making a diy nano calcium reactor from an oxygen line humidifier.
