I'm a big fan of refugiums, for all the reasons you mention. They offer a natural alternative to using technology and chemicals. Not only that, when it's mature and full of life it becomes a second viewing area, sometimes as interesting as the main display.

melevsreef I've done the same thing many times, although the refugiums I've had have never looked as nice as yours, I do love critter watching, it really is a peaceful feeling. I've always liked planted freshwater tanks (I've never owned one) and having a refugium is kind of like having the best of both worlds, reef tank display and a nice macro growth in the fuge. I've got a JBJ 30 RL and I'm growing mangroves in the back at the moment but I'm making my list to upgrade to either a 60 cube or 65 gallon RR. I'll definitely include a nice refugium in the build. I've always wanted to have a dedicated refugium system that would gravity flow down into the sump. I saw one that my LFS was using and I loved the idea of having a sumo that had to stay behind closed stand doors. Having a display refugium is like having a clean engine bay on your car, compared to a refugium that works, but it's really dirty and not something you'd like seeing.

melevsreef Do you ever worry about your feather caulerpa going "sexual" under your reverse lighting schedule? I started doing some research online and the forums seem to think that a reverse lighting schedule would make it go "sexual" and some said 24 hour lighting would prevent it but as soon as you turn off your 24 hour lighting that would trigger it to go "sexual" as well. I'm drawing up my plans for a sump and I'll probably do something like you've got with the protein skimmer in the back left area, refugium running across the front portion and then the back right portion as the return pump area. I'd like to use some feather caulerpa as well, its an aesthetically pleasing macro algae, I'll probably also run chaeto as you are along side the caulerpa.

Hey... Thank you for sharing all your videos. I dont have a refugium for my tank, but I u used to grow feather caulerpa algae in my sump... I used to grow like crazy, because I had nothing else to filter the nitrates and other nutrients....later on I added some stuff that took my space and I just couldnt keep the plants in it. While I had this algae in my sump, I used to constant give some to my fish... They did love it (not sure is good or not for them, but they DO LOVE eating chaeto and feather algae). A month ago, I found out about this little refugium that I could hang on the side, which I thought I was a super cool thing, so I bought one; I went to get some chaeto, but after a week, it seemed to be getting white and dying, and I had to removed half of it. After doing some research, I got to the conclusion that maybe I didnt have the right light for the chaeto (I was using the light that came with the little refugium box).... Yesterday I got a different kind of light that stimulates plant growing, and I also got the feather algea.. I really hope that works. By the way.. I am in California and I have got the feather caulerpa algae from a local fish store... I didnt know it was a typed as pest in the State. Thank you for all the tips and info. By the way, your tank looks amazing.

The "Hot Pink" light you mentioned is usually a blue LED with a red filter and garbage and I agree. HOWEVER, there are some lights and cob chips you can buy that are true multidiode lights. The best ones have reds blues etc but also infrared and ultraviolet diodes. Those are the real deal, they do have a pinkish hue because of the red and blue but the ultraviolet (which you don't get from white LED's) actually penetrates deeper into the chloroplast layers of the plant tissues. My friend has a tank with t5's and he switched one of the 2 bulbs to a UV and noticed his carpeting plants were growing faster in his freshwater. 395nm+ is great for plants, the diodes with UVB's can be too much and also bad for human and animals eyes. Staying higher in the wavelengths is safe while still reaping benefits. BTW, your video was very good and you explained everything very well and I also love the feather caulerpa!

Does algae actually benefit from increased co2 levels? I thought it was only true plants that did...but my background is more in high tech planted tanks where we run excess co2 to give the true plants more growth potential over the algae that we deal with so perhaps in a system without true plants algae can utilize the co2 better?

Just a quick note, oxygen does not increase ph, it's the removal of carbon dioxide. CO2 + H2O H2CO3 H+ + HCO3 HCO3 H+ + CO3 According to le chateliers principal, a buffer system will shift to reach equilibrium, therefor the removal of CO2 from plants shifts this buffer system to create more CO2, reducing free floating hydrogens and so it increase PH

It's when the plant bleeds out all of its green fluid within into the water column, and the mass turns clear. Within a few days, the clear plant collapses, falling apart as you try to remove it.

Micro algae is Hair Algae (derbasia) or Bryopsis. Caulerpa and Cheato are macro algaes. The taller the refugium, the more lighting is needed to penetrate the water. Some have reportedly thrown tons of wattage at their refugium and see massive growth, so there is validity to lighting choices. People have used T5s, VHOs, Metal Halides to grow these plants, but LEDs are the less energy-consuming choice of course.

This type doesn't. Caulerpa nummularia is much more prone to go sexual, but if you keep the light on 24 hours a day it won't. But you don't benefit from the pH boost since photosynthesis can't process naturally. www.melevsreef.com/node/447 I don't feed macro algae to my fish because there's a chance some of the plant can pass through the fish and land in the rockwork to take root.

I see I see. Do you happen to know the exact type of caulerpa that you have? I was thinking on adding the one from Indo Pacific Sea Farms, they sell a yellow and red one that they use to feed their tangs but I have seen many people with great reefs like yours or Duane's using caulerpa that make me wonder if I should just use caulerpa instead.

Feather went sexual in my tank. Lol. But, I'm a certain kind of special!

Hi Mark, I run bio pellets and wondered is there still a benefit of setting up a refugium in my sump? I do like the way you can grow your own pods though :)

I run both since each offers benefits to my reef. If you have the space, incorporating a refugium is a good choice.

Whats your opinion on sulfer reactor to help control nitrate? Or do you think adding a larger portion of the sump to more macro would be more effective?

I've still never used one. I borrowed one to try out, but my tank was back to nearly 0 nitrate so that test would have been pointless. I like biopellets, they have made nitrates a non-issue for my reef. Macroalgae does all the nice things I mentioned, but you'll notice I didn't discuss it helping reduce nitrate since it never did in my own system.

Hi. Nice video. Would like seek some advice from you. If i am dosing trace element to the reef tank. Do i need to dose more if i have a refugium? The algae will absorb some of the trace element in the tank i suppose? Please correct me if i am wrong.

Just dose what the tank needs. Don't add extra 'to be safe', and consider that if you can't test for what you are dosing you could very well be using too much as it is.

So do you in any way try to "rescue" pods when you take out a hunk of macro algae? Or are they just a casualty of cleaning? And color me in the category of living in California and being pissed that some dummy dumped it in southern california and now everywhere in the state it's banned. Don't get me wrong I'm sure chaeto can do the job, but the "green steel wool" look doesn't look anywhere close to as nice as macro that has rooting capabilities.

I used to try to shake out the macroalgae to scavenge the pods, just like some people try to find all the ones that are trapped in their filter socks. But unless it's crawling with them like ants, odds are the few you lose won't after the population *that* much.

Hi Mark, I am a big fan of your videos and a subscriber for a long time. This one is another great one! I have been trying to keep cheat in my refugium but unfortunately the whole thing just seems to get smothered in GHA and turn brown. My refugium at the end of 3 months just turns into a mess of GHA and starts polluting the water column with tons of GHA filaments (I believe it is derbesia). I have always had near zero Phosphate (0,018 according to latest Triton test) and zero Nitrates. I have heard that macro algae needs Nitrates to grow and a zero Nitrate tank tends to have GHA issues. Would love to hear your thoughts on this 😊

Macroalgae needs nitrate, phosphate and iron to thrive. The lower those numbers, the tougher it will be for plants to grow. Assuming you have a nice strong light for the macro, it could just be the tank lacks what the plants need currently and you've got to get those parameters in the target zones. I'll be talking about those this Saturday. Suffice it to say, my tank has some nitrate and some phosphate. I run biopellets and use Phosphate Rx to keep the numbers reasonably low.

You're definitely right that zero/low nitrate and phos tanks likely have more gha issues because there is usually an unnatural ratio of nitrate to phos. Gha is simple and doesn't require as much as other algaes to grow, so it can thrive with less of either, consuming whatever trace amounts of phos/trates aren't being used by coral, at levels so low we can't see them on tests. We see zeros, but those trace amounts are enough for the gha 👎🏼. Feeding macros in a separate area is the basis of a refugium, but people forget to feed, leaving only enough nutrients for simple gha algaes to grow. I've run a low nutrient tank, while keeping a refugium happy by "feeding the fuge". This can be as simple as feeding the tank more, dropping a few food pellets directly into the macros, or dosing phos and trates at very low levels directly to the fuge. I've done all 3 of these things without seeing phos or trate levels rise. There's my 2 cents, and now I'll anxiously await Marc's thoughts with you :).

I use brightwell neonitro and neophos mainly on macro/seahorse tanks, but want to clarify that I would first try the pellets in a reef refugium. A little nitrate and phosphate goes a long way, and dosing either can cause a lot of harm if you don't test like crazy and go VERY SLOWLY in a refugium. I have only one reef with refugium, and multiple macro tanks. It's easy to forget that people don't love algaes as I do, and use them only for nutrient control. Refugium algae like caulerpa and chaeto might just need better lighting or iron, as Marc pointed out. If you use red macros like Gracilaria, potassium can make a huge difference also. But, for a low nutrient reef tank refugium, I would personally try adding the pellets, feeding more, increasing or changing lighting, adding a little iron or potassium (based on testing) and only try dosing nitrogen if none of those work. Feeding a fuge actual food is much simpler than trying to find a sweet spot dosing products. Sorry for the change of direction, but I wouldn't want you upset with me if your algae thrived, but coral died. Last comment: although a refugium can be beautiful and very helpful in reducing nutrients and algae in a display, if your tank likes to grow GHA, an algae scrubber might be perfect for you :). Same concept of using the algae in a separate location to keep the DT clear, but you already know you can grow GHA no problem, lol. Saves space too!
