Gorgonians

[coltrref]

(13/04/2009)

i was considering several changes ranging from reef: skimmer, flow, lighting and renovation of the living stone in its entirety and is also likely to increase the volume to 450 liters.

I was concerned the issue of flow, and had acquired two seio M1100 (1100gph/4400lph) with your controller.

the seio initially were thought to be at the base and rear of the aquarium to sweep away the detritus and this is part of the diet in a more suspended, but he had doubts whether to place them at different heights and configuration specified in ON/OFF.

at that time had two Koralia #2 and #3, more 4 powerheads connected to wavemaster of redsea.
4 heads of power were in the bottom-rear of the tank removed.

Also in May 2009 there was news.

I changed my decision, I acquired the first WaveMaker of Hydor with 4 Koralia 12V instead of seio and wavemaker.

There was also bad news:
if you know the cause, some gorgonians watched them with some anomaly between the polyps, or rather in the coral tissue, parts dark.

Some gorgonians iodine baths

Grolux anticipates comment that was bad news

was no information. and I thought it was the same infection and presenting the same symptoms, but had no ofiuras, which probably was the cause of aspergillosis.

Echinogorgia (2), Menella (1), Guaiagorgia (1), Verrucella (1) were passed quarantine.
Verucella (1) Muricella (1) Plexaura (3) have passed to the large tank. (died)

at the end I found this information by Katharina Fabricius and Philip Alderslade:

Nutrients

Particulate and disolved nutrients originate from very fifferent sources in oceanic and coastal water. Oceanic Waters in the tropic are chronically nutrient-depleted by planktonic growth and associated grazing processes, hence they Are clear and blue. However, currents sporadically push cool, nutrient-enriched, deeper water up the slopes of continents and atolls. Such upwelling significantly boosts the concentrations of available disolved nutrients in offshore surface Waters, although frequencies and extent vary widely between regions. Such regions are often denominated by xeniid soft corals (Fabricius and De'ath 2000), wich have been shown to take up and use disolved nutrients (Schlichter 1992 a, b). In shallow coastal Waters, food concentrations are more variable and often higher than offshore, because of the terrestrial run-off of nutrients, and the resuspensión of bottom sediments. In wet tropical areas, nutrient-and sediment enriched river Waters Floyd into the sea, enhancing concentrations of nutrients and sediments, and stimulating phytoplankton blooms and microorganismo growth.
Such areas tend to be dominated by alcyoniid soft corals in the shallow water (irradiance becomes limiting at greater depth). In many parts of the tropics, Waters pollution is considered a major distrbance for coastal reefs.
Chronic discharges from sewage outfalls, and run-off from deforested and agriculturally used land add nutrients, top soil, and pesticidas to the coastal Waters. Run-off is said to contribuye to the decline of nearshore ecosystems, and depending of the on the ectent of run-off, problems have been recorded from the shore to tenso f kilometers off the coast. Most zooxanthellate soft corals are Messing in higly polluted areas, and those azooxanthellate gorgonians wich are able to grow in polluted areas, often show high susceptibility to fangal infections, colonisation with algae, barnacles, bryozoans or anemones, and a high level of parcial mortality.

In the Caribbean, the fungus Aspergillus, wich is typically associated with terrestrial soil and does not sporulate in sea water (Smith et al. 1996), causes widespread infections and mass-mortalities in Gorgonia ventalina an G. flabellum. The mass mortalities were linked to large river floods importing high sediment loads (Garzon-Ferreira and Zea 1192), and chronic infections were discussed to be a consequence on increased sedimentation from soil erosion (Nagelkerken et al. 1197)

and my bad luck a Billeeanum Epitonium

14 gorgonians died

I said almost all the water from the aquarium with partial changes without adding any additives.

of which were in quarantine, was Verrucella tissue recession and the other was under observation, but fortunately I survived many more without infection.

I observed the following hypothesis according to information from E. Fabricius K Borneman and organic waste tends to promote certain pathogens and is very likely that changes in the currents have awakened the demons to remove them.

continue with the chronic ............

(29/06/2009)
for what happened with the deaths of some gorgonians and then the lack of light for several hours, I decided to change all previously cured live rock and although it would not be permanently leave the pictures to the memory before switching to larger tank .

apparently gained too much rock, but all will be fine for the sump.

Some gorgonians back to tank:

(22/07/2009)

3 gorgornias np's back in the aquarium where there was too much light and there was one release of tissue in some parts.

Thanks very much for sharing colt.

So if I understand correctly, you did water changes that eventually saved some of the gorgonians (please tell me if I misunderstood)

Some questions:
- did the iodine dip help at all?
- during this time of infection, what were your phosphate and nitrate levels?
- how often were you dosing the foods eg phytoplankton etc...
- were you carbon dosing?

I believe that I first had to remove the infected sea fans.
second step, to make partial changes in the belief remove fungus from aquarium.
third step, remove all waste or detritus from the base of the tank.
fourth step; carry quarantine treatment of gorgonians with little visible infection and give them baths with reef dip of Seachem, but separating those that do show infection.
during treatment with iodine in the gas tank, joanxavier (Moderador in e-Coralia) warned me to try to control it:

Controls levels of iodine, when I had the great mortality of gorgonians in my tank, I read that these store iodine in the tissue as toxic to defend against predators. At death, it passes the poisoned water column.

and at the same time I recommended the following:

I think it would be wise to start thinking about a good load of activated carbon.

so I immediately installed four reactors in line with activated carbon.

Food was only once a day.

during this time of infection, the NO3 before and during infection did not exceed 5 mg/l.
I'm sorry but do not perform testing is PO4.

I doubt how this Plexaurella fragment, which by its large size and weight despite the current side will received continuously even sustained a heavy stone.

(I have several gorgonians fragmented, but especially this type of stock I have much respect and that the thickness of the "fabric" I think the bad cut, may cause it to loosen the tissue and die)

with the advice joanxavier and j.alberto, fragmentation of the method did Sally

(17/09/2009)

my wife gave me a Diodogorgia nodulifera:

current images of the moment:

Joanxavier,

have already been fragmented because some of the gorgonian, but especially the large, yet to make the first cut was not needed to tie the fabric.
and even this morning even though they are under observation, ALL, the polyps are open.
then upload images to observe the cuts and methodology

This procedure was inspired by Sally:

plugs

drilled 1/2 cm incustar the stem of the gorgonian.

then the base would be cut, and remove tissue.

cutting the base.

two drops of cyanoacrylate and embed the stem and stick, leaving in this way.

however, other gorgonian fragmented several branches, so it was before the court:

and stuck in stone:

of the same species, to take two pieces cut and pasted into plugs and this is one of them:

 

[coltrref]

now go with the biggest and that worried me the cut on the tissue thickness, which certainly could get four fragments.

this is the image before the court:

with the court and made the first branch, I also get another frag:

following the methodology of Sally, I was hitting and this was the result of one of them:

stay this way could also get another frag:

Hello colt.

The gorgonians are excellent, and I see you left the forums in Spanish. But it is good that you are in a better forum.

Let's see when we can see your aquarium?.

I stick a couple of non-photosynthetic corals and I need your support.

I hope we can meet soon.

Congratulations on your gorgonian

Sweet!

beautiful gorgonians!
hey question this seems like the place to ask...
I'm setting up a seahorse tank and I'm looking into getting some gorgonians I'd prefer to get photosynthetic gorgs just so I don't have to dose as often the tank is a 29g ponied onto a 75 reef tank via a shared sump. I'm going to use 2-3 power compact bulbs and thats where the question lies..
everything I see on them says that most need medium to high lighting.. but I see people using power compacts on their tanks with gorgs... to me high lighting is a metal halide.. (like in my 75) just wanted some feedback =)

thanks
I have illuminated photosynthetic gorgonians HQI tank at different heights, and I think you have problems with power compact, if so, whether the gorgonian need more light, raise the position.
three compact power sources, only one that is either all actinic 50/50

luck with the project

 

[coltrref]

Sweet!

thanks slapshot

 

[flying_dutchman]

Beautiful gorgonians, do you have a FTS (full tank shot (picture of whole tank))
Could you tell me the name of this coral?:

 

[coltrref]

sorry for the delay but work trips I have been unable to answer your question.

I can not say if the gorgonian in mention is Euplexaura, Menella or Echinogorgia. :blown:

 

[coltrref]

this is a Echinogorgia and was some of which survived the disaster:

other more..........

the day following the fragmentation (22/09/2009):

one week after......

 

[coltrref]

I do a jump to the history and put a few almost current images

 

[coltrref]

this way he was almost one year ago before the change of aquarium

great tank!

great tank!

thanks Alex
