Hi guys,

Could someone please confirm if this is the dreaded dinos?
Struggled with diatoms and what looks like dinos ever since I had to move my tank 2 months ago.
I’ve now had to removed the the sandbed and doing as much manual removal as possible by blasting rocks each day and rinsing floss.
Also tried chemiclean which helped with a bit of cyano and ran actinic only for 3 days or so.

Never had this in any of my reef tanks in the past. I’d like to know why it happens as peramters we’re always good until I moved the tank. I’m guessing it released some phosphates and nitrates from the 2 inch sandbed.

Coraline hasn’t managed to take off very well so far so I’ve just blended and added some from my bros tank.
If hydrogen peroxide is the way to go then I’ll certainly give it a try.

H2o2 is not the way.

Please check in over here: Dinoflagellates – Are You Tired Of Battling Altogether?

I recommend getting some microscope pics and posting in that thread for a more specific ID. Get the $10 toy microscope mentioned in that thread if you don't have one. It'll let you view up to 1200x.

Also make sure you read the whole first page and investigate at least some of the links there before you do anything.

Thanks for your input mcarroll.
With the changes I had made by removing the sandbed and blasting the rocks and coral with a powerhead each day the algae was definitely receding.

I haven’t done a water change for 3 weeks and also upped phosphate to just 0.03 and nitrates up to 5.0. I also pulled 2 reactors off line using rowaphos and phosguard.
Now back to chaeto and putting plenty of mixed foods in and see how it goes.

I have used 2 half doses of Dino ex and it’s all gone so will keep an eye on the tank at least 100 times a day as usual.

Very pleased to see some great progress at last as I’ve heard stories of people having to pull their tanks down and I’ve never had this before.

I believe this was either caused by me having to move the tank and upsetting the sandbed or it came in on an un dipped frag

How does hydrogen peroxide affect an ATS? I would imagine it would kill everything off of it and would have to start all over again.

H202 breaks down quite fast in salt water. It oxidises anything it comes in contact with be it dinoflagellates, turf algae or some bacteria....to name but a few examples. It’s not specific to anything in the aquarium.

Technically it could kill the algae but As most are housed in a sump I would expect it to have neutralised by the time it reached it. Still it does remain a possibility.

It may not affect it at all. But you might want to either search for a related thread (this one's on dinoflagellates) or start your own thread if you can (I see you're brand new - welcome!!) so you get more eyeballs on your question.

Good luck!

An alternate explanation for oxidizers helping deter Dinos is oxidation of certain trace elements, such as iron and manganese, reducing their solubility and bioavailability to the Dinos.

So, it’s 1 ml/10 gal of the regular 3% hydrogen peroxide you find in any drugstore?

What are the side effects on clams, pods shrimp and snails?

@five.five-six You may want to flip over to the Algae forum and check out this sticky thread:
Dinoflagellates – Are You Tired Of Battling Altogether?

At least read through the information in the first post and check out as many of the links there as you can.

Above all, make sure you know what you're treating....verify with one of the tests in the first post that you can do with almost no equipment that it's at least some type of dino. Or ID by way of microscope. (Lotsa folks using $10 scopes....not a big deal...best way to ID anything.)

At the top of that thread, I have linked a much larger experimentation (i.e cure) thread where everything from h2o2 to bleach (yes....I know...right?) was extensively tested for miracle-curativeness. Results were conclusive – dino's are cure-resitant as heck!

You can run a search on that thread to see how often out of the 4000+ posts that h2o2 was tried by different members and see how many times dino's came back for them. (time saver: All verifiable cases of had dino's return.)

I think they are dinos... here is a video of their family reunion

The one on the left has had wayyyy too much to drink and making moves on his cousin... and she's only 16 minutes old... pervert!!!

You might want to post that up in the main dino thread for more eyeballs....

I had been letting the dinos grow on the glass to keep them off the coral, rock and Sans but today the glass turned green great news because I think that means the algae is now kicking Dino butt!

Not sure if it was mentioned but bivalves are known predators of free swimming dinoflagellets. Might be worth a shot.

My LFS doses Hydrogen Peroxide on his display tanks for all nuisance algae’s and he’s got some of the best looking tanks I’ve seen around.

Still trying to identify my dino's. There might be a couple types in here. The ones moving about tend to orbit around a center point.

Thank you for posting. I’ll keep this in mind if I come across this dilemma myself.

I decided before I would restart my tank due to a number of issue;

Byropsis
Dino
Vermetid snails
Aquascapes

I took my GFO offline and within a few days my Dino vanished, I then spent the day removing the majority of my rocks, scrubbing them clean of vermetid snails, bryopsis and rescaping, what’s interesting after mixing up some of the sandbed there was no webs like there normally is, I imagine the population died off but the stems still obviously remain.

Two days after a 25% water change and not a single sign of Dino.

Vermetid snails all clear and just waiting on fluconazole to arrive to kill of any remains byropsis.

Really it’s amazing just what I have had to deal with and still enjoy the hobby.

My question is this. Was this just regular store bout Peroxide that you can get from Walgreens or something like that?
