Hello I'm new to the site starting up a reef tank. Currently have a discus tank and apistogramma tank,I've kept reef in the past. Going to be a 34 gallon Mr aqua rimless. I need filtration looking at eshopps nano cube sump my question is does the refugium section do anything its on the small side or should I be looking at a different sump my space is limited so it would have to fit. Thanks walts o
