Need refugium lighting? Here's some! brs.li/Fuge_Lig...
Today on BRStv, we have a brand new episode for our series, BRStv Investigates. In this series we explore popular reefing theories, products, methods, and what the manuals are missing, with a focus on putting them to the test!
In this installment, we put Chaetomorpha to the test and discover some surprising results! We tested four refugium scenarios with four different fuge lights and quickly found how effective they were at removing nutrients in the tank. On top of that, we made some educated guesses on proper sizing of a refugium that may turn the fuge size conversation upside down!
So stay tuned and join the larger conversation as we take a closer look into the effectiveness of a refugium and refugium lighting, give you a new perspective on nutrient control, and help make reefing a bit more fun and easy for you and your tank.
There’s much more to investigate as we continue this series, so keep an eye out for future episodes where we test bulb efficiency, aquarium heater accuracy and more!

As a marine biologist, I give my approval of this test, as this is based on scientific fact, and not guesses.

For a refugium light what watt light would be to much lets say 1000w led im just wondering And what's the lowest watt can be used thanks

@KlimovArtem1 6 лет назад

Great test. I can confirm that even smallest Chaetomorpha refugium can make a big difference. I run it in a small back section in my Nuvo 20. There is a constant water flow and I provide very bright light (LED). The algae doubles every 1-2 weeks and I prune it regularly. I don't run any skimmer or other filters, no reactors, no gfo, only filter socks. I feed generously and let nitrates swing between 5-30 ppm, but phosphates are always undetectable. And grow SPS ! So, my tiny Chaetomorpha refugium definitely works. No hair algae in display. And, btw, as soon as I started the refigium after cycling the tank few months ago, I noticed a quick the drop in nitrates (from ~50 to just 5ppm), and there was no light yet in the display at that time.

@reptilewizz 3 года назад

This is one of my favorite videos of yours to date especially since most of the conversation in regards to the benefit of refugiums is mostly conjecture. This is an awesome start to really nailing down whether or not what many of us are doing is really working or not. Thank you!

@sethswheelhouse 7 лет назад

BulkReefSupplyCom You guys are amazing! Instead of blindly supporting the various sides of the hundreds of opinions in reefing you roll up your sleeves and practice real science to provide real answers. Good thing too! I added a Cheato reactor to my tank last night! Its great to know that it wasn't for no reason.

@Jotto999 4 года назад

I don't even want a saltwater tank, but this is damn interesting! So well made.

@patricktucci2818 7 лет назад

Great video. I would like to bring up another topic for consideration. What you've actually done in this test is set up a 25 gallon refugium solely for chaeto. While this is a good reference (a 25g fuge with chaeto, proper light, proper flow, etc, can handle a cube of food per day), it means a few things. First, if you feed a cube of food a day and want results like those seen in the video, you may need to set up a 25 gallon fuge solely for chaeto if it is your only filtration method. Second, if you feed more than a cube a day (some reefers over on Reef Central are feeding upwards of 5 cubes a day), you may need to provide many times more space in which the chaeto can grow. Another thing to maybe consider is micronutrient profiles in the foods you're feeding. There has been some conjecture on forums that chaeto growth may slow or stop entirely without proper micronutrients, such as iron. It appears that the food you are feeding to these tanks has a complete micronutrient profile that completely satisfies the need of chaeto, but it is possible that other foods won't contain this perfect mix, and may not grow chaeto at all, or maybe not as well. Another consideration is that you are feeding an empty tank. In a tank with live animals, it's possible the animals will use some of the micronutrients that the chaeto needs. After the food is excreted as waste, it may no longer contains the "perfect" nutrient profile, which could result in slower growth than we are seeing in these videos. Again, good work, and I think "cube equivalents" is the best way to discuss chaeto's nutrient consumption profile. I was personally surprised at how well the chaeto did, even with the cheap clip-on light. I just think we may want to keep in mind how complex different tank environments can be, and that your mileage may vary.

@Forgetii 7 лет назад

For myself, I found this episode one of the most interesting. When I first started using a Chaeto refugium I had a significant explosion in growth. After time and thinning the Chaeto, I've noticed my growth is significantly less. I attribute this to the Chaeto removing a large amount of nutrients from the water and once stabilized the growth matched the available nutrients. I for one think that a refugium is definitely a must for reef systems. Great Video!! I'm glad you guys are on top of the things we as Hobbyists need to know.

@bif24701 7 лет назад

No way!!! just look at the topics being posted on the forums. Folks are really starting to ask and discuss very complex topics.

@sethwilliamson 7 лет назад

One of the issues with algae that I'd be interested to see tracked (Seneye?) is the impact on nutrient levels post-harvest and what percentage of biomass can be safely removed without impairing the nutrient export to a concerning level. We've all learned that sudden changes are usually bad. In other words, exploring (a) letting a chaeto ball grow huge then removing all but a handful, versus (b) more frequent but less aggressive pruning, and the impact on tank stability.

@obct537 7 лет назад

Cheers Ryan and the gang for doing the science, so we don't have to! Really amazing work. I'd love to support you guys when you start shipping down under! ;) I removed my chaeto to observe the effect about 6 months ago, and what I saw was a noteable increase in nitrate levels, which had been unreadable for the year until that point. It definitely does something!

@MatthewWagnerNOECA 7 лет назад

@ReillyPerovich 7 лет назад

chaeto has always helped me get and keep nutrient levels down

@MannyDer 7 лет назад

I have a bunch of chaeto in the bottom of my sump, below the filter pad. It's not technically a refugium, but works much like one. I have two tanks (60 & 40) on that one sump. I'm using a curly bulb during the night. I haven't ran a protein skimmer in about 10 months. I also have a 100 gal with a refugium in the sump, I run a waterfall style algae scrubber instead of a skimmer, also about 10 months or so on that. Everything is running great, big fan of chaeto

@ospreys48 7 лет назад

In reference to how size matters, my Refugium is a 150 gallon Rubbermaid tub for the DT which is 344 gallons. I believe it has been very beneficial and has allowed me to get away with a lot such as very little water changes.

@ospreys48 7 лет назад

And lighting for the fuge is a 8x39 watt T5 FW (white and pink) with bulbs that are about 5 years old. I certainly would not be using this lighting if I didn't already have it lying around but quite impressed with how fast the cheato and caulerpra grows

@johnwilliams4806 Год назад

Thx I seen a video about the same things that Ryan was talking about and this video really helped me make a decision that every few gym is beneficial for my tank and there are more things to consider than just the size of the refugium .. I was strongly, considering canceling my order of clean Kato from algae barn but after this video, I see that they refuse gym is beneficial for me. Thanks, Ryan much appreciate it.

@samin2012 2 года назад

@npviking 7 лет назад

so one cool test would be exposure time. I briefly saw a plan to make a "winding path" for the refugium where the space for the refugium turned into a long winding chamber (3 sections if I recall) to give more exposure to the chaeto. now that doesn't change the flow rate so the actual exposure "time" remained the same but it allowed for more forced exposure to the chaeto.

@AMILLER415 7 лет назад

I love my Chaeto! I have a CPR hang on fuge with their LED light and I added 2 trays of miracle mud. I pull out a big ball of chaeto every week and put it in my compost. It works so well that I quit having to run GFO in my reactor and currently just run Carbon. Now I'm seeing my phosphates and nitrates above zero and many of my corals, especially my mushrooms and zoas are opeining up and getting bigger! My SPS and LPS also look happier. I've started feeding my fish more and supllimentally adding powdered coral foods and acropower, as well as the red sea color and energy programs. My thinking is that I like a variied diet, so my coral will as well. I'm beginning to feel like I'm getting to the Goldylocks Zone. Slowly dialing in my setup. My problem was I was running things too clean, but now I'm balancing things out. It's amazing how effective the Chaeto works for keeping phosphates down for me and it looks like your results so far are looking fairly promising! Great work on your testing setup! It looks like it's going to be an awesome series!

@DanielHJeffery 7 лет назад

I'm building a shallow 60gal acropora dominant tank and going to rely almost entirely on Chaeto in my 40 gallon sump, no skimmer, no GFO. In the past I've had most success feeding very heavy (feeding coral not just fish!!!!) and relying on algae for nutrient export, unparalleled color and growth compared to any of my low-nutrient tanks using mechanical and chemical filtration. :D

@Eaglefires 2 года назад

So I've actually found that using 2 or more macro algae is the best approach. If one type isn't absorbing a particular nutrient, the the other will. Key is adequate lighting and flow.I recommend cheato and sea lettuce...bonus the lettuce can be harvested for herbivores in your tank.

@Quiksilver5451 7 лет назад

@Dennco2000 7 лет назад

Thanks for all the hard work. I know this type of research is very time consuming in addition to your daily job duties. I had been searching the web for info pertaining to this but could not find anything nearly this extensive and controlled environments. I use the fuge2 medium on a 65 tall salt... Works great and grows chaeto like crazy with a small aqueon 36 LED light so now Im thinking about replacing it with the Kessil a80 tuna. As for results 3 months after adding the fuge and micro algae the Ni/Na nothing zero. Phos runs 0.02 but I also run phosguard but very little. prior Na was always about 5.0. Thanks again Dennis

I've watched less you tube for a while but now I'm back super into it and really glad you guys are still doing so much for the hobby. 👍

@ShilpanGPatel 7 лет назад

As someone with 6 fish who feeds half a cube a day, I've found a refugium of chaeto and caulerpa keeps nutrients near 0. I wonder if more than 1 cube would be still manageable? I also love the pods this produces to feed my fish so I'm a fan :) Seriously great video BRS I appreciate your scientific vigour and thouroughness good job!

@JosephThompson619 7 лет назад

I've tested multiple spectrums and different styles of lighting on my refugium over the past few years so I found this video to be very informative. I'm not a professional reef keeper or any kind of marine biologist. Just the average saltwater aquarium hobbits with a few different types of salty setups in a Michigan basement. I've tested PAR38 LED's full spectrum, RED, 5,000K and 10,000K... Grocery store brand CFL curly bulbs @ 6500K daylight spectrum as well as 6500K & 10,000K T5HO lighting. I've found that Cheatomorpha grows best for me under 6500K spectrum CFL or 6500K TH5HO bulbs with a high flow rate in my refugium. So much so that I was actually trading in a giant 5 gallon bucket full of cheato to the local coral farm like clock work each month while using this type of lighting. Just a quick note that CFL & T5HO should be changed out after 6 months of normal use. Macro algae removal is my primary source of phosphate and nutrient removal since I've moved away from skimming around 9 months ago. While running similar experiments on my macro algae display tank, I found that T5HO 10,000K bulbs gave me the best growth with the more desirable types of macro algae like dragon's breathe for example. The red types of macro seem to flourish and benefit the most from a more blue/white spectrum 10,000K light. The 5,000K LED daylight bulbs did a fair job at growing cheato but nowhere near the growth rate obtained with 6500K CFL or T5HO.

@dangappa 7 лет назад

larger masses of algae will also provide more surface area for nitrifting bacteria, so culling the cheato is probably a good thing.

I love this channel and I don't even have a reef tank,it's the science that turns me on! I've had a 125g tank sitting empty since xmas due to blown discs in my neck and with all that I've learned on this fantabulous channel I will be in fine shape to setup my own reef tank or a fwolr tank when the time comes.

@-Tac0caT- 7 лет назад

Excellent. Very much like the idea of increasing food supply to determine uptake differences, if any. I am also very interested in seeing how they level out, as the nitrate levels were not level at all. Also, I would like to see the actual par readings for those lights. In my refug, I used a cheap 6500k 100 water cfl. It didn't seem to work as well as when I had a 5k led. So now I run both and the macros are growing strong. Both bulbs said they produced 1000 lumens, but I think the LED was significantly better about directing all of that down into the refugium.

I feed one cube hikari mega marine algae and one cube cyclopeeze daily. Plus feed 1" square of mysis to my anemone every other day.

@IS-db6pn 7 лет назад

BulkReefSupplyCom Definitely support Marty Adamo's comment. I would love to see how a Chaeto Reactor fairs in these experiments. I have considered a lot implementing one because space is very limited in my sump but have not as I haven't found helpful data or results on their effectiveness like what you are doing in this series. We appreciate everything you do for the hobby.

@Travix03 7 лет назад

I actually put together a DIY Chaeto Reactor and have been running it for a little over 2 months. I don't have anything to back this up, but I would hypothesize that it's much more efficient than a clump of chaeto sitting in a sump. I think that's the case since more of chaeto is getting light and it's all good flow. Just my 2 cents, but I do think it's worth a look! Great video!

@martyadamo1 7 лет назад

I am referring to reactor like the Skimz or a DIY reactor. The Pax is much to rich for my blood but I would be interested in the Skimz or turning a standard reactor into a chaeto reactor.

Wow that PAX is pretty cool recommendation, and it seems like maybe the only algae option when you are talking about a < 12G nano w/ no room for a sump. Is that supposed to grow chaeto, or hair algae like an ATS?

Cool, thanks! I am currently experimenting with a DIY hog turf scrubber in my nano and it's definitely not working any miracles :(

In my progression of the hobby I've come to really support refugiums with chaetomorpha as a supplement or even alternative to other nutrient exporting methods such as GFO. That being said, I am still quite surprised in the seemingly positive results so far. Very curious to see this experiment develop over the coming months as well as the tests with MarinePure!

Another interesting test point is, get 90W worth of $5 CFL bulb, see how that compare to kessil. So that's about 4 100W equivalent bulbs.

If I miss this in the video I apologize. What is your lighting schedule? You cover the idea of a reverse photo. Well I just enough these lights Ron for eight hours a day 12 hours a day or what. Thanks for your awesome job on this great video. Very informative and great to see scientific basis for a lot of our anecdotal practices.
