Refugium Maintenance Do's and Dont's

[Enrique]

Should the macro algea be cleaned from all the detritus that gets stuck on it?
There are so many pods and living fauna in for example cheatomorpha Macro algea.
But would it become a nitrate factory if not cleaned?

Hello Enrique! That is a very good question. I like to disturb my fuge as little as possible. I do keep the glass clean, but allow a little algae to grow for my snails and I use a turkey baster now and then to blow off heavy sediment on my LR. I also once in a while will use a shish kabob skewer and insert it into the macro algae(I have a large quanity of spagetti ) and give it a little shake to lift off any heavy sediment, all of which rises into the water and is transported to my filter mediums and then to my skimmer. I don't want to disturb my fuge too much as I do not want to heavily decrease the populations of various pods there. The macro algaes and other life forms in the fuge are living off of these nutrients that are coming from your DT. And of course I am no expert, but this is the method that I have found that works best for me and the set up that I have. All systems are different. I will maintain my regiment like this as I have a growing population of mini serpents and they appear to like the fuge and help keep it clean. I meant also to ask you.... do you have snails and any other life forms besides the pods in your fuge?

Hello Enrique and to TR.

I routinely harvest the caulerpa in my fuge and occasionally harvest cheato, this serves to keep them free of detritus. I would not want debris building up in mine. What kind of macro are you growing?

[Enrique]

I am growing Caulerpa on one corner away from the cheatomorpha that I am also growing. I have a lot of snails in my display tank and I have no snails in my Refugium. Are snails beneficial in the refugium?
Will they do any harm to the living fauna in the refugium?
Can they remove too much algae from the glass and starve all the pods that are always crawling on the walls?
Or on the contrary remove more nitrates by eating the algae?
Do snail feces contribute to nitrates?
I also have another question in which I have found contradicting information all over the internet.
Are bristle worms bad or beneficial for you refugium? I know there are diferent size bristle worms and different species. I also learned that the most common found in aquaria is the fireworm species. I recently Added a piece of live rock to my refugium and I quarantined the rock and noticed 4 bristle worms that were about 2 inches long and about 1cm wide. They had a red pigment and I proceeded to remove them. Better safe than sorry. After adding the rock I noticed really small bristle worms crawling in the refugium millimeters wide and about half a centimeter long. Should I hesitate to remove them? I have read in some places that bristle worms are good scavengers and that they do not kill other species. I also read that people missunderstand them because when they see them eating pods in general they think that they killed the pod but the reality of the situatiion is that either the pod was already dying from starvation or was scavenged and missunderstood.
I am so confused by other sources of information were they say the contrary.
Is removing bristle worms part of my refugium maintenance?

Snails are beneficial in the fuge and I routinely keep them there. They will eat film algae off the macro. Bristleworms are good detrivores and a valuable part of your clean up crew. I don't think they eat pods unless they are dead.

As CarmieJo stated, snails help keep your fuge clean and are a welcome addition. It is just a matter of preference.

Snails will not harm your macro algaes or your pods as they love that green algae film. There are several different varieties of snails and some are well known for keeping the SB loosened and free of detrius. My macro algaes grow so fast I could have a macro eating monster in there and never know it. Many people will "trim" their MA to help it grow more and also to remove any dead or dying sections as they consume nitrates and when they die they release those nitrates back into the water. (This is my understanding) I would not be concerned over snails' waste products being a factor in the nitrate equation unless they are dead and/or decaying.

As CarmieJo stated, bristle worms are good and some consider them part of the clean up crew and are not known for eating corals unless they are dead or dying. Some people make an effort to "remove some" when they have a population explosion by manually removing them or by introducing species of live stock that are known to prey on them. I also have them in my Nano and DT. I have only removed 2 so far and that was because they had grown to 8" long in my nano and I had so many. I have some 3" to 4" long come out every time I feed my nano and I like it because they help remove any uneaten food during feeding. They are actually a beautiful animal if one ever really takes the time to examine them. The babies start out to be the typical brown and red bristle worms, but when they start maturing and growing, they turn into a beautiful gray with irridescent blue and pink hues. Hopefully if yours grows another 2 inches you will be able to see the awesome color combinations.

Here is a link to a thread that has photos of bristle worms and one of the members stated that it was highly unlikely that a person had a "fireworm" versus a bristle worm.



There is a lot of "Information" as well as "Misinformation" out there in the public and on the web. I personally will take the advice of someone who is a successful reefer and has been in the hobby for some time any day over something I found on the web or what someone at the LFS told me. I take all information and thouroughly research it. As CarmieJo so eloquently stated one time. Look at the source, and if all those agree with it, then it is more than likely quite accurate. (Advice here on TR) Hopefully others will chime in on this post and give you their HO and suggestions and ideas that were not discussed.

Worm or Parasite?
