My 36-gallon bowfront tank is currently cycling and I would like to set up a hob refugium. What would be the correct size I would need? I can't do one that goes under the tank and with the center brace the tank has, that leaves roughly about 13 inches on either side. I was thinking about getting a small CPR AquaFuge 2 but wasn't sure if that would be big enough or if there were better options. And if I go with that refugium, would this light be sufficient to grow chaeto?
