Tube Fuge on TalkingReef.com 8/1/07
Hi Crew,
<Hi Brian, Mich here.>
What do you think about this:
http://www.talkingreef.com/forums/podcast-episodes/3413-diy-cryptic-tube-fuge-video-podcast-episode-88-a.html It's basically a PVC pipe stuffed with live rock rubble. There is a low powered power head in the display tank pumping water into the vertical standing PVC pipe beside or behind the display tank. The water rises and just overflows over the edge of the display tank. It's a 3-gallon cryptic refugium with lots of surface area for sponges to grow on. I am just wondering how effective a 3 gallon cryptic refugium could be.
<Interesting idea. Anything helps...>
I guess if there are many sponges in it, the effect could be a decent amount of nutrient uptake and secondarily, a small population of pods.
<He reports lower Nitrates...>
Any opinions?
<Got lots! Though I doubt you care to hear most of them... maybe these... Pods are good...the video was long...Samuel reminds me of Alton Brown... Mich>

In Tank Refugium?    5/15/07
Hey all! Thank you so much for creating such a wonderful site. In my eyes it is the end all be all of aquatic information. Anywho, I had contacted you guys a while back about a mysterious string of Lionfish deaths and am happy to report all is well now. After a 100% water change I have been able to keep an Arrow Crab, Scooter Blenny, and a Dartfish (who is due for another mate as soon as my LFS gets one). Allow me to redescribe my set-up: 25g FOWLR, Eclipse lighting/filtration (carbon/Purigen/PolyFilter-in lieu of a skimmer), 35lb LR, 40lb 2" Arag bed,
<Heeeee! Not much room for the water!>
160gph powerhead, 3 red-legged, 4 blue-legged hermits, 3 snails. So, to the matter at hand. I may be crazy for keeping a Dragonet in such a small tank (which you no doubt have already determined), but this is my goal; to not only keep the Scooter but some Mandarins as well.
<Mmm, don't mix well... behaviorally or micro-niche habitat, resource partitioning wise...>
In order to feed the little guys I plan on breeding Amphipods, Copepods, etc (I know I shouldn't nor do I want to mess with live brine shrimp and Selcon).
I have no overflow and therefore no economical or feasible means for a sump or external refugium, so I was looking into an in-tank refugium (which I could easily manage). There are premade ones on Amazon that look incredibly simple. What is you're experience with these and are there any serious drawbacks compared with a conventional design?
<Yes>
The dimensions are 7.5"X7.5"X4". It's small but so is my tank and fish population. Please tell me as much as you can (in layman's terms) considering I have absolutely no experience with this level of fish-keeping and it's my first marine tank. Would the regular lighting/cycle (30W, not sure of how many Kelvins; 10-11hrs/day) from my DT be suitable?
<Yes, but...>
I know I should add live rock, sand and all that good stuff, but what type of algae should I add?
<Likely either Chaetomorpha or Gracilaria...>
If you could just run down everything else I need to know I would be forever in your debt. Again, thank you so much for everything and I hope to hear from you soon.

<Well... I do wish you had a larger system period, or that you'd get one... Or that you'd add another larger volume to the side of the present one and make one or t'other a/the refugium... Please give this area another read re: http://www.wetwebmedia.com/marsetupindex2.htm

In tank refugiums   10/27/06
Hi, I have a 24g AquaPod reef tank. Aqua C remora protein skimmer and various corals. I would like a refugium but I do not have the space, so would an in-tank refugium work?
<Mmm, yes... but you don't have much room/volume to start with here...>
I would separate the macroalgae from the predators with a rock formation.
<Okay>
I was wondering if it did work, would it be not a beneficial use of space because of the small tank. And if you think I should do it, any suggestions on how to do it and what macroalgae would work best?
<Is posted on WWM...>
I tried the links before I asked the question and could not find an answer. Thanx, Chris
