Purigen in a reactor or a refugium?

[GHOSTLY]

Oh jeez, I wouldn't change a thing. It looks pretty good!

Are you having algae issues or something?

Actually I shut that tank down a while ago and just got back into the hobby. Didn't have horrible algae issues and didn't get an ato, dosing system, or anything till its final months. New tank is set up and I plan to get coral right after this wc
