The tank I'm currently cycling is a 20g and I decided against a HOB
refugium. My main reason was price and effectiveness. I can build one in a 10g that will hold my heater, more macroalgae, live sand, live rock, and give microfauna a larger safe haven for around $50, where as a HOB
I see starting at around $90 for one with any real water volume. Just my opinion and reasoning, either way I think a refugium will help stabilize my system because of increased water volume and a reverse light schedule to help fight pH swings in the night time.
