Does this work for a sump design. It is what i already have set up on my FW and it works a treat. Would it be O.K for SW. Excuse my ignorance but what exactly is a refugium ? What do i need to do one and what type of light would i need and how long would it have to be on each day ?
Is it true you don't need a protein skimmer if you run a refugium ?
Thanks
