Dinoflagellates my experience......h2o2 reefing tool!!!!!

[reefknight]

I'm having a difficult time eradicating dino's in my 185gal display. I have tried the standard reduced lighting, reduced feedings, water changes, GFO & GAC, increased skimming, etc. I have used peroxide in the past to kill different macro algae's but as a dip with great effectiveness. I haven't attempted to dose the tank before though and am looking for someone with experience in dosing. The display is overran at this time with the dino's and is attempting to strangle out some colonies of corals. I have ended up in a rather deperate situation. I have been reading up on this subject as well as Fauna Marin Algae X as another option as well. Any assistance would be greatly appreciated.

pH- 8.1
Alk - 8.6
Ca - 480
Mg - 1700
PO4 - 0.08 (Hanna)
NO3 - 0.50
SG - 35%

These are growing on my background...they can be up to 6-7 cm sometimes.

Can you upload some higher res images? I suspect its cyanobacteria.

Has anyone heard of urchins eating dinoflagellates?


I had some in a tank of mine and I was cleaning my sump and threw both my urchins in that tank and now I don't seem to have any dino in that tank.... Is it possible. How reef safe are urchins. Both are pencil urchins.i think.lol

It will likely depend on the type of Dino you have. Ostreopsis (one species I've identified as causing blooms in reef tanks) creates a toxin similar to palytoxin. Amphidinium (another reef tank Dino pest I've identified) also creates toxins that are harmful to sea urchin.

 

[whitekenyan]

Hmmmm. There alive and moving and I don't seem to see any dino anymore.

I'm going to try and get you a sample this week. Probably ship out on Tuesday. Ill send more then one sample just in case shipping gets alil rough

Great. Since it sounds like yours isn't toxic even to an urchin who scarfed down a bunch I'll be very eager to ID it. I'm hoping its the tiny one I haven't figured out yet. If space in your package permits give me some tank water too (but only if you have space).

Dino's?

I don't think anyone will be able to say from that photo. I'm guessing it is brown and goopy and catching those air bubbles we can see in the picture. If that is the case there is a good chance its dinos. But any clump of photosynthesizing algae can get oxygen stuck in it that way so it could be cyano or green algae. On a macro level the easiest way to tell the difference is color. Can you remove some of it from the tank and photograph it under daylight?

It blows off easily but it comes back lol. Cause the peroxide isn't working. It's been a few days now but I didn't change anything so I don't know the cause

Mine look similar. Here is what I have tried
-6day blackout - wipes then out but they come back
- 2ml per 10 gal h2o2 3x a day- no real effect
- both methods above used together- no real effect, they come right back
-fauna marin algae x in addition to huge black out. - killed all algae but no effect in Dino's.
- nothing has worked. I have had them 3 months now and have resorted to just blue light in my tank. Mine look like the ones in the above pic.

Mine is actually green now Sooo annoying lol

 

[EpicWin]

mine too

 

[whitekenyan]

If it stays low to what ever its attached to then def not dino. When out stretches like 4 inches and looks like snot. then you have Dino

I am new to the forum, wanted to thank everyone for this thread I am on day 8 of peroxide dosing and my Dino seems to be completely gone. But...... What I need help with is what happened after. My fuge now resembles a swamp. Green algae and Cyno took over the whole thing none of this is present in my DT and it is as clean as it has ever been in the 5 months its been set up. So my question is what should I do with the fuge? The nuisance algae is choking off the cheato which had good growth the 1st 5 days or so after blackout and peroxide dosing the DT. Should I let the stuff run rampant down there and exhaust itself or should I try to remove it? My fear is that if I take steps to remove it in the fuge, nuisance algae may take hold again back in my display tank. I have a 40G DT and a 29G fuge and am running a dual BRS reactor with carbon and phosgaurd. Thanks for any recommendations you guys can give me.

Yes Dino
Been battling it for a longgggg time. It starts like what you have in the pic and if you let it go it will start to look like snot.
If you have the lights off for 24 hrs it will recede or disappear. But its still there and will come back. Also have you notice a lot of gunk building up in your powerhead when cleaning it? Take another powerhead (like the old maxijet) and while the first one is going direct a strong current all around the intake areas and see if gunk start coming out.
The cure that some people have had success with is most likely because they didn't have Dino
I've been doing and all out attack on mine and it's looking good (fingers crossed) I have 0 signs of dino and all my corals are looking soooo good. They haven't looked that good in along time.

Mines all gone. Guess I got it before it took off. Tank is crystal clear my barebottom glass is sparkling !!! Corals look great too!! I kept lights off for 2 days

 

[Nammy]

That's great, how long has It been gone for? After my first try with lights out it came back slowly after about a month so I hope this time is gone for good.

 

[bigcapct]

A little over a week. Knock on wood lol

What's Dino?
