Some Ostreopsis there swinging and hanging on their flagella.
You got a good shot of it on pic 1, close to the bottom. |

Unions are your friend. They're expensive, but they can make a complex reef into a system of LEGO-like blocks. Flexibility and ease is key. In case of crisis, they're always there when you need them. They got your back in the middle of the night when nothing else works. It's a true friend that waits patiently and responds immediately when you call on them.
((Tearing up here with emotion))... No, seriously - use them. I understand the sponge loop. I use my chaeto and cryptic zones to create a flow of life. There's always some flow through my cryptic zone, but it's ~1/10th my main flow that's about 4000gph... so maybe 400gph? That's a guesstimate since I can't really measure it. The featherdusters are parasitic... they grow everywhere. The coralline prefers darker environments. It grows far from my halides. The cryptic zone only gets the faintest light refracted though the acrylic front. I think that there are difference species of coralline... I haven't found the one that likes direct intense light. Interesting concept of an algae-dominant microbiome... Need to think and read up on that.

funny you mention high nutrient low chlorophyll (HNLC) research. a couple of weeks ago, I realized how relevant HNLC was. It's what I've been aiming to create in my water column - available macronutrients and light, but with some crucial micronutrient(s) removed actively by chaeto/caulerpa leading to low dino growth. It's cool to find what I was doing was well researched in big sections of the ocean - once I realized what it was that I was doing. :-) The HNLC phenomena is still debated, but Fe or Fe+something are the overwhelmingly favored explanations. That lit helped me narrow my trace element search list. Quote:

Once dinos essentially vanished from my tank in the last 2-3 weeks, Coralline growth exploded - completely covering the back glass, alk has now dropped precipitously. The dino months prior showed only a trickle of Coralline growth in spite of abundant Ca/Alk levels throughout. It never got so bad as to have coralline turn white and die, as others have reported. There was no dosing that could be credited for the change. Quote:

Also this paper on Fe in seawater is unintentionally hilarious in that it's several dozen scientists basically throwing up their hands repeatedly at the complexity of trying to say what forms of Fe really constitutes "bioavailable" and who uses what, and how once in an organism it changes and is used by the rest of the system.

Also, cyano needs to just chill. It's into every sketchy thing. It's like the organized crime family of the ocean. Any rare, valuable, desired resource - N, B12, Fe whatever - there's a cyanobacteria dealer on a corner somewhere selling his goods.
At this point it wouldn't surprise me to find out cyano has a hand in booze, drugs, and prostitution. Actually it has been associated with vodka dosing so... |

I'd keep alkalinity above 7 dKH at the daily low. You could go lower, but it's definitely a tightrope walk.

As dinos declined, coralline growth took off, covering my back glass which gets direct sun - didn't expect it to thrive under straight sunlight. Few days ago a couple of corals closed, I realized coralline seemed to have slowed, tube worms and clams didn't have much bright white new growth at the end of their growth area, so I tested water again - 6.1 dKH. (420 Ca) So I added baking soda. Spreading it over a few days, since I'm going 6 to 9. |

Cool thanks. I tested mine this morning, 7.0. I aim for 7.5. Will ramp up dosing a little more. |

I was thinking that judicious use of GFO could keep P under control without stripping it out of the system, but I'm still quietly freaking out over DNA's observation... Quote:

The silica is unexpected -- since you mentioned not looking for diatoms, I'm guessing it was the Sundown Naturals that triggered the dino collapse... Did you use the NatureMade on the first run? Quote:

display tank ---> macro/ATS ---> cryptic biofilter ---> display tank But that Tank of the Month implements a cryptic sump with an unusual split flow, and there are hobby blogs and threads describing systems with intriguing sump layouts and Calfo-style RDSBs and cryptic fuges and whatever else that might work just as well. I'm sure there are reefers out there who've been capturing the benefits of the sponge loop for years without ever having heard of it because they're good hobbyists and good observers and they go with what makes their livestock happy. So let a thousand flowers bloom -- I have no wish to be the arbiter of how to correctly set up a cryptic biofilter. This is the closest I've come to speaking to that point... Quote:
Sponges don't like microbubbles, BTW, and generally speaking, they do like Si. About 75% of sponge species have siliceous skeletons that don't readily dissolve and recycle if they die -- sponges can potentially live for centuries, perhaps thousands of years. Diatoms normally outcompete sponges for Si in the wild, but a "sponge scrubber" may give sponges enough of an unfair advantage to compete effectively. It would be interesting to try a cryptic biofilter in a system with a persistent diatom problem and see if the sponges can turn the tide. Quote:
Another approach would be to dose your live sand tank with OTC B12 every day for a week, and every day take a sample of sand and put it in a beaker with osti-infested sand. A shift from the healthy live sand being taken over by ostis to live sand killing ostis might indicate the presence of dinocidal bacteria -- or it might indicate that your ciliates are all pumped up on B12 and ready for a fight. You might be able to tell the difference by looking for an increase in the ciliate population, as presumably the smaller the bump in ciliate numbers, the more dinos fell to bacteria, instead. But maybe I'm fixated on green algae for no good reason. If the silica in Sundown Naturals B12 really did trigger the growth of diatoms, it's pretty impressive that they managed to rise up and defeat the ostis without any outside help. Dinos eat diatoms, and diatoms are presumably not okay with this, so they're probably friends with dinocidal bacteria, too. Maybe that's where to look for help -- after all, diatoms evolved after dinos, meaning they had to beat dinos so they could take their place in the sun. In the end, green algae lost that fight.

I like the idea of finding biological allies. I think that's at the heart of what we're doing already.
Understanding what makes them allies and then experimentally proving how and why they behave is the tricky part.

Runing zeovit from day 1 with the thought that ULNS would help curd the unwanted algae and beautiful garden of SPS, After getting rid of the algae infestation a month ago, with 3 dose of Coral snow but immediately followed that was something I can't id + really bad case of dino. I have completely stop the dosing of zeostart and sponge power 2 days ago as I feel that the dino were prqbably consuming that to grow even faster. I am still maintaining the zeo reactor at 100gal/hr rate, add combination of 4mL of coral snow and 4 drops of zeobak after dark.
What should I do now, take zeovit reactor (vibe) off line since the mule released may even fuel the dino more? what do you guys think, I've read that zeozym + biomat might help, if so I should administer with zeobak and coral snow, please help!!!!! Really want to get rid of this ugliness. [/QUOTE] |

Oh wow. How old is the setup? If it's new, I'd just drain and start over with new live rock and sand.

Took a sample of water with the slimy stuff, and took a video for everyone to enjoy, I can now confirm that they are indeed dino, the question now is how to kill these little buggers. I subsequently diluted the sample with half of RO/DI and the pests are gone, but I can't just dump my rocks with various frags of SPS for water bath can I ?

If it's early enough in this tank's life, I'd start over. You need new life.
Get new live rock and sand and start over with a normal bacteria and algae cycle. Be happy when you see the diatom bloom and the hair algae... Then slowly tune it down to normal. Your images show the worst case I've ever seen.

Its about 3 months old, and started with dead rock, should I go bare bottom.
Can you kindly suggest live rock source I like something porus, thanks. |
