So unfortunately set up a new tank a few weeks ago and didn’t monitor no3 very well and it bottomed out….. started with mostly established rock. Is this ostreopsis?

I don’t really know how Dino’s look like microscopically, but if they form “sheets” and disappear when lights go out then yeah, it’s dinos

I’ve had amphi Dino’s on the sand bed….. these do disappear mostly through the night but some big strands hang together all night…. Just fired up the uv so hopefully that helps…… a new system with new sand do half expected it to be diatoms but this stuff is pretty thick

UV should help especially at night when Dino’s enter the water column. Could be a mix of GHA since you mentioned a strand. Not really sure though

Definitely have a bit of gha too but the strand I was referring to are like long strings of slime sticking to everything

Yeah probably Dino’s then

Thank you!!

These are pr

These are Ostreo.
Its biological deficiencies that are causing these dino structures.
No light is first key followed by the addition of bacteria to overcome the bad bacteria allowing them to thrive
Prepare by starting by blowing this stuff loose with a turkey baster and siphon up loose particles. Turn lights off (at least white and run blue at 10-15% IF you have light dependant corals) for 5 days and at night dose 1ml of 3% hydrogen peroxide per 10 gallons for all 5 nights. If you dont have light dependent coral- turn all lights off. During the day dose 1ml of liquid bacteria (such as micro bacter 7 or XLM) per 10 gallons. Clean filters daily and DO NOT FEED CORAL FOODS OR ADD NOPOX
You can feed fish as normal and if doing blackout, ambient light in room will work for them

Thanks again for your help!!! Will uv help much with this strain? It’s a 25 gallon IM lagoon aio system. I have a bigger aio uv unit I threw in the tank but makes pretty high flow! Almost too much….( can also just take the bulb out and place it in the back compartment and cover it so no light escapes… and all water passes by it as the back wall is opaque black)

UV Will help but understand that UV addresses what passes through the water channel and will not get all the cells.

Well I will keep it going. Do a small w/c today and suck up as much as I can, and implement Everything else you suggested tonight. Thanks for your help!! Appreciate it and one more question. Should I just try to keep my nutrients at 10 no3, .1 po4 while doing all this too? Thanks

Those are ostreopsis. They move around as if they have the pointy end "tethered", right? Proro are round. Ostreo are GENERALLY the easiest to solve for. A properly sized UV with SLOW flow will do wonders. They are also the most toxic of the bunch so running some GAC is advised.

I wrote this article back in early 2022. Sorry for the long read but it should help.

ostreopsis for sure.

ostreopsis for sure.

Agree- looked on larger screen and changed it

thank you for the clarification. You think I should mess with my lighting since it’s ostreopsis as well or keep it normal for my coral?( bumped it down to 20 % normally running at 50, and killed the whites. )
I am familiar with the guide and appreciate the help. Thank you!!!! Will still add bottle bac daily and keep an eye on all my nutrients! And you think hydrogen peroxide would still help out at night?

Ostreo are pretty good swimmers at night relative to others so no need to adjust lights for them really. Whatever keeps your corals happy.

I am not familiar with the H2O2 method honestly. I don't understand the impact of dosing a mild oxidizer would have on dinos. Maybe it does something help spur the growth of other surface competitors? IDK.

Nice, guy from a aquatics store told me I just need more clean up crew for my Dino’s, after charging me 40$ for a 1oz bottle of corals rx & 250$ to hang my light from ceiling and glue like 5 corals

Cleaner crew will not clean up dinoflagellates. Some will be effective with cyano, not so much Dino

 

[kweigum]

Anyone know that these worm things are with the Dino’s? Almost seem to be eating them

Hey! So I kind of did a mix of your and Scott’s methods and it seems my Dino’s are gone. ( knocked my lights down, used uv, used h2o2, dosed a bit of silica( not enough to induce a diatom bloom, dosed Phyto and dropped in a ton of pods) and after 4 days not a trace of any ostreopsis in the tank that is visible…( nothing in filters or skimmer!!

thank you, my animals and I truly appreciate it!!!!! Couple questions

Have my lights slowly ramping back up over the next 15 days….
Only did 3 days of h2o2. Should I discontinue since I can’t see any more Dino’s?

How long should I continue UV? I don’t really like running uv 24/7

And when do you think it’s safe to resume waterchanges/ clean my glass up?
