refugium benefits for corals

Post by flumen »

I've been thinking about adding a refugium to my 75-gallon tank. Does it really help with nutrient export for corals? My nitrates are sitting around 10 ppm, and I'm not seeing the growth I want in my Zoanthids.

Refugiums can be a game-changer, especially if you're struggling with nitrates. I run one with Chaeto in my 120-gallon, and it keeps my levels at 5 ppm or lower. What's your lighting schedule like for the fuge?

I've heard mixed things about refugiums. Some say they're worth it, others think they're overkill. My tank's only 40 gallons, so I'm not sure if it's necessary. What do you guys think?

Yep, Chaeto's a beast for nutrient export. I run mine on a reverse light cycle, 12 hours opposite the display tank. Keeps pH stable too. Flumen, what's your current filtration setup?

I'm all for refugiums, but they can be a pain to set up right. Gotta make sure you've got enough flow through the fuge, or the Chaeto just sits there. Also, pods love it, which is a bonus for the tank.

Honestly, I just threw some macro in my sump and called it a day. Not sure if it's doing much, but my nitrates are kinda chill, so maybe it's working? Tank's a mess otherwise, though.

Thanks for the input, everyone. I'm running a canister filter right now, but I'm thinking of switching to a sump with a refugium section. Vimster, reverse light cycle sounds smart—I'll try that.

Canisters are fine, but a sump gives you way more flexibility. Just make sure you've got enough space for the Chaeto to grow. It can get out of hand fast.
