Building Your Refugium Clean-Up Crew

byKenneth Wingerter

No one ever said that keeping reef aquaria is totally uncomplicated.Especially keeping them clean!Sure, some maintenance approaches are simpler than others!manbetx3.0最新natural methods are, for example, fairly effortless means to control nuisance algae, detritus and pests.

Natural methods certainly requiresomeresearch, planning and occasional monitoring!but for the most part, they involve adding organisms that improve environmental conditions simply by doing what they do… naturally.For youmanbetx3.0最新, this eliminates much need for tinkering with touchy equipment, changing expensive chemical filtrants, constantly algae wiping, etc.Plus, successfully creating a dynamic, self-sustaining ecosystem is hugely satisfying.

manbetx3.0最新Perhaps the most common and most important agents of biocontrol for both algae and detritus are copepods.This should make plenty of sense, since these tiny crustaceans fulfill the same ecological role in most natural aquatic/marine environments.Increasingly, aquarists are taking all kinds of measures (e.g.phyto dosing) to ensure that their systems can sustain large copepod populations.Arguably, the surest way to promote high copepod density is to install a planted refugium.

Planted refugia (specifically the macroalgal "plants") already have other, well-known benefits!they reduce dissolved nutrient concentrations, for example.These are considerable benefits, for sure.But planted refugia are worthwhile for their pod-promoting properties alone.

So–by cranking up pod numbers, a refugium helps to keep a tank clean.That doesn't mean that the ‘fuge itself can't get dirty.For example, massive accumulations of detritus can form in densely planted refugia.And pods can't control pests.Like in the main tank, the best way to tackle refugium cleaning and remove pests is to adopt natural methods.

But planted refugia are necessarily different environments from the main tank.This means that many animals used for clean-up in the main tank cannot be used in the refugium.For example, urchins are excellent algivores that are great for the display, but can't be in the ‘fuge because they'd eat all of the macros!There are just as many species that are safe with macros, but aquarists just don't think to put them in the ‘fuge.Imagine what happens if you put a gazillion aiptasia-eating animals in the main tank but stock none in the refugium–you'll probably never get rid of the aiptasia, right?

Again, overall, a refugium makes it easier to maintain a clean, healthy reef tank.But yourtank will beeven cleaner, witheven less effort, if the ‘fuge houses its own clean-up crew.

Obviously, planted refugia are brightly illuminated environments.manbetx3.0最新Thus, even in such close proximity to their macroalgal competitors, nuisance microalgae can take hold there.It can grow on the glass, on the sand or even on the macros.manbetx3.0最新A well-rounded group of algivores can control these bad algae.manbetx3.0最新This must, however, not include any animals that might develop a strong taste for your macroalgae.Sure,somesnails might eatsomesoft macros likeUlvamanbetx3.0最新, but it's all good so long as they focus on the microalgae.

There are a few captive-bred snails that are suitable for this purpose.Not only are captive-bredtrochus snailsandsiphonaria limpetsmanbetx3.0最新both excellent algae-eaters but they also are much hardier than wild-collected specimens.

For Detritus

Particulate organic matter (POM) is highly prone to settling out in refugia (especially planted refugia) where flow is reduced and certain macros (especially meshy types likeChaetomorpha) act like mechanical filters.This isn't necessarily bad.For one, it removes these solid wastes from the display tank, where they would otherwise be much unsightlier.Also, by settling POM in the refugium, it is concentrated in just the spot where most of the pods are (i.e.where they can eat it most efficiently!).

Still, in tanks with lots of well-fed fish,detrituscan build up faster than the pods can consume it.This is where the pods can use some help.Detritivorous snails are perfect for this job.Again, because wild snails can be touchy, captive-bred specimens are a much better choice.Thankfully, the sludge-bustingcerith snailandnassarius snailclean up crews are available as captive-bred.Tiny burrowing snails such as these significantly improve the appearance and water quality of a reef tank, and indeed refugium, by consuming organic wastes.manbetx3.0最新Most of these also contribute to some film algae control as well.

For PestsAiptasia is a Common pest in the marine Aquarium

Many small invertebrate animals are used to control pests of various sorts.Most of these are quite happy to live in the ‘fuge.The list of pest control critters is a bit long to run through in its entirety here, but we'll posit thepeppermint shrimpas a great example.This is, for sure, due to its proven usefulness in eradicating a common and particularly nasty pest, the aiptasia anemone.But these shrimps are also pretty good at scavenging wastes in general.This would include larger chunks of organic matter such as fish food that might find its way into the ‘fuge.These guys can mop up in seconds what would take copepods hours to do.This is especially important when snails die in the ‘fuge!apeppermint shrimpwill eat a dead snail long before it has a chance to decay and foul the water.

Conclusion

Your refugium clean-up crew may be built around your specific needs and specific type of system you have.manbetx3.0最新But regardless of the details, it's a really good idea to remember the ‘fuge when your stocking critters for algae, detritus and pest control.This undoubtedly will simplify your maintenance regimen and reduce your reliance on complicated, expensive filtration technologies.And of course your tank will be a whole lot more interesting to observe!

    i thought that we WANTED to keep these things in the refugium, so i have never added a CUC to the refugium, rather give these pests a place to grow freely so they stay out of the DT.

    I never thought of having snails in the refugium but I think that I will add some besides the pods.

    I have thrown a Mexican turbo snail in the fuge before… didn't think of any other CUC.Will have to boost the crew!

    I will have to try some snails in the refugium and see if they help along with getting more for the tank.

    Excellent ideas.Will try snails and peppermint shrimp in my refugium.Assume they don't mind the constant light?

    The biggest issue I have with my clean up crew is snail poop it builds up so fast and is super ugly in a flat bottom tank.it's a white ashy looking pellet and sinks right yo the bottom.

    Great article!It is very challenging to keep refugium clean!I definitely need to add more pods and snails.

    I've never seen peppermint shrimp before!They're so cute.Complete ecosystems always interested me, especially the jar terrariums.I used to have a huge pest snail problem and then got a feeding dish and that's helped me a ton, my cherry shrimp do the rest.

    Clean up crews are absolutely essential for any saltwater tank.In any tank build-up, I start with the clean up crew and work my way up.

    I had an urchin in my refugium for a while.manbetx3.0最新My macro algae still had to be trimmed up frequently.manbetx3.0最新I think it liked the coralline algae covering the sump more.

    I'm looking forward to installing my first refugium soon.I have spent a lot of time researching what is best to use and it seems much more beneficial to the system than.a bunch of chemicals.

    Wow there's so many options to work with then.This minimized the amount of equipment needed to maintain your tank giving it a more natural look.I think I might switch to salt water.I don't feel like I have as many options with fresh water.I learned so much just trying to apply for the contest.I honestly didn't know that much about salt water tanks because I'm still pretty new to the hobby.Thanks

    I have had many if these critters over the years but the best $30 I ever spent in my life was for an aptasia eating filefish.I had hundreds taking over my tank and tried Tha aptasia magic wand, laser and almost every other product to get rid of them.Couldn't use shrimp because I have wrasse.The filefish ate the all in less than a month.

    I think a display fuge is an awesome way to go and if you have cool clean up crew all the better!

    I don't have a refugium in my current tank, but I have 4 hermit crabs, 2 emerald crabs, 2 sally lightfoot crabs, 2 peppermint shrimp, and a lawnmower blenny that help to keep my tank spotless.
