Hello, I set a fluval evo 13.5 3 months ago. I'm pretty sure its fully cycled based on tests. I was curious if a refugium worth it in this tank? I have the inTank media baskets in chamber 1 & 2. I've never set a refugium up so if you could give me pros v cons. Also if you think I should what kind of light, algae, tips, etc. could you recommend?
