What about a cryptic fuge? Those seem to be all the rage. Can you still have a pod population in there?

Watching this thread closely as I am considering starting one up. I did see this debated at a conference with Julian Sprung definitely in favour, but he did indicate that there are so many different definitions of what a fuge is, so it makes it difficult.

You can definitely run a successful reef tank without a refuge, but that doesn't really mean much. We have all seen successful tanks run without protein skimmers, carbon/GFO/other media, filter socks etc... there are just so many different combinations that can work.

- My old tank had a refugium run on an opposite lighting schedule to the display tank. It kept the pH extremely constant.
- Depending on the species of algae you grow, I think even small refuges can remove significant amounts of nutrients.
- They consume CO2 and produce oxygen. Elevated CO2 has been known for decades to reduce growth in aquatic animals, but seems to have only recently started to gain traction in the salt water aquarium hobby as being an important water parameter.
- From a husbandry perspective, if you take care of the refuge it can make a decent place to keep aggressive fish, fish that need to be target fed etc.

I vote YAY as well. For me, I run a 150 gallon refugium conveniently located over my sump. It has sand, live rock, dead coral rubble and grows pods, algaes, all the good stuff ! :thumb:

Fuge over the sump? Do you have a pic?! :)

Dammit man... -___-

lol

Yes, as a matter of fact I do. Here's a recent pic of my 150g 'fuge.

Most incompetent fuge I've ever seen. Where's the Chaeto , Caulerpa and Miracle Mud?

Ya, it's definitely far from perfect :sad: I struggle with growing Chaeto as my tangs seem to enjoy (consuming) it, immensely. Plus, I have a hard time finding Caulerpa around here. Seems no one wants to stock it anymore. Instead, I have to settle for bubble algae and film algae. The Miracle Mud is all under the live rock. It's only visible when you lift up any rock allowing the "mud" to escape all over the place clouding the entire refugium. :neutral:
