I think it's virtually impossible to be 100% sure they won't be back no matter what you do so in my view the option is to clean up and sterilize everything (tank and equipment) as much as possible, with bleach and fresh water, run the tank on FW for several days and go from there. Old sand has to go. Rocks, they have to go too unfortunately, unless you do some bleach/acid/fresh water treatment to them and take your chances. I would think what becomes critical at that point is not to re introduce the bug. No old sand/rocks, dip corals and fish, all that. Try to have good bacteria, algae, good critters well established before introducing fish and corals. And yes, pray for the best...
Sorry for new developments. Lemme read back through all your posts, and see what other clean method options make sense next.They do this often on meI would really like to know whats my new enemy after ostreopsis disapeared.
If you have some digital scales could you crush a tab and separate 1/10 (whatever 1/10 weight is) and add to 5 gallon test sample in say bucket with heater (if cold). Would need light source as well.
Thanks for taking the time to post that!!
Have you seen Table 1 from this article?
Programmed cell death in protists
Haven't posted that one to my blog (yet – it's goin' up!) but here's a few key excerpts from the table:
Table 1.
Apoptotic markers in unicellular organisms
Organism | Conditions/inducer | Apoptotic markers
Symbiodinium spp. | Heat stress [15] | Chromatin condensation; intact plasma membrane; vacuolization and vesicle formation; cytoplasmic condensation [15]
Peridinium gatunense | Decrease of dissolved CO2; H2O2[16] | DNA fragmentation, cell shrinkage; increase in reactive oxygen species; late plasma membrane permeabilization [16]
Amphidinium carterae | Darkness/light-deprivation [17] | Cell shrinkage; vacuolization [17]
Interesting to see why some of our treatments may be working.
I don't recall anyone trying systematic CO2 reduction, though I think I remember it coming up as a hypothesis or suspected solution at some point....that coulda been in the context of another thread about cyano, etc tho.
Worth looking at that CO2/H2o2 reference for sure.
Looks like the darkness treatment is probably related to Amphidinium blooms.
Anyway, it's a big table, so there might be more items of interest.
Was thinking about this from the perspective of what we know about Symbiodinium and heat stress.
A linked article from the Stress section of my blog...
Limited phosphorus availability is the Achilles heel of tropical reef corals in a warming ocean
Even if you just read the quotes on my post, you see that the heat alone does not spell doom for them. It's a set of circumstances while under heat stress. (BTW, that's an amazing article from soup to nuts IMO.)
So, reducing CO2 by kalk dosing or light-deprivation treatments are almost surely not enough by themselves either.
Has anyone read citation #16 or #17 for the pest dino's yet to see what they found?
It's a very interesting coincidence that phosphorous-limitation – not over-saturation – is the lynch-pin for dino infestations, cyano infestations, as well coral bleaching.
(Corals seeming to be little more than a concentrated, semi-controlled dino/cyano infestation.)
What scoop do you recommend and where should I buy one?I see you have a scope on the way!
It should be standard with today's aquaria
