Everyone,

I?m hoping someone can help me ID this algae that?s been cropping up in my display tank and sump. At first I thought it was the beginning stages of Cyano but I?ve been doing some research and I?m starting to think that it might actually be Dinoflagellates. The algae is long brown stringy and has trapped air bubbles. I first noticed it on the frag rack but now its starting to spread over the rocks and my coral and I found some in the sump.


Here?s a little background on how I got to this point: I made the mistake of putting a small frag of pink pulsing xenia into my tank in December of 2014. Long story short, it totally overran my tank and was growing everywhere. I did some research and I decided to dose my tank with Fenbendazole following the instructions that the author of this article https://maxdraco.wordpress.com/2013...ue-cloves-polyps-xenia-aiptasia-hydriods-etc/ used to get rid of his infestation.



It actually worked and cleared my tank of all Xenia but the die off caused my phosphates and nitrates to increase and now I?m dealing with what started out as a turf algae bloom and appears to be turning into dinoflagellates.
After the Xenia die off I started doing water changes every few days until I turned over the entire volume of my system. I?ve also been running Rowaphos and carbon aggressively and swapping them out every two weeks.



My nitrates are back to normal but my phosphates are still high.
I?ve also been dosing the tank with Special Blend every two weeks and Nite Out after every few water changes. Also, on 7/3/15, I started using kalkwasser in my ATO to maintain alkalinity.


As of 7/9/15, my water parameters are as follows:
Nitrate: 2-5 ppm using Red Sea test kit
Nitrite: undetectable using Red Sea test kit
Ammonia: Undetectable using Red Sea test kit
PH: 8.4 ? 8.5 using Red Sea test kit
Phosphate reading from display: 0.08 using MI 412 low range meter
Phosphate reading from reactor: 0.20 using MI412 low range meter
Calcium: 460 using Red Sea
Mag: 1500 using Red Sea
Alkalinity: 10.5 using Red Sea
TDS: 0ppm I use BRS 5 stage RODI unit
Salinity: 1.025 Currently using Red Sea Coral Pro salt


I thought the Xenia battle was going to get me out of this hobby but now it looks like this algae bloom might be the straw that breaks the camel?s back.
Any suggestions on getting rid it?


Thank you all for taking the time to read this.

That is one of the worst things to get.Try starving it out and run lots of gfo and carbon.Water changes make it worse.Try 24 hour blackout

Does it look like Dino to you? I've read that its a serious PIA to deal with. I haven't done any water changes since I spotted it.

I really thought my battle with Xenia was going to kill me but this might be what finally does it.

It does.
You can beat it!

Check out the all articles from advanced aquarist regarding dinoflagellates, just be very diligent in beating it down.
Remember its photosynthetic and loves nutrients.

Ugh!!!!! Thanks Chefjpaul. I guess I should have mentioned my lights. I'm using ReefBreeders Photons currently set to max out at 70 percent white and 65 percent blue. They turn on at 11am and ramp up throughout the day and shut off at 11pm.

I'll be sure and check out those articles on advanced aquarist. Thanks!

Yeah,
They recommend like a 72 hr. Black out. Along with some manual removal, GAC,
Etc....

maybe look into a bio clean or something, (I don't know if that is answer or will work, but worth researching).

I feel like I've been kicked in the gut. Just read an article on Advanced Aquarist. I guess I'll be starting the blackout this weekend.

Patience my friend.
You'll be fine. Just takes time.


I started the 72-hour blackout last night. I have the tank wrapped in brown paper bags but I noticed that the temp is running at 79.5 degrees. I normally keep it between 78 - 79.

Should I be concerned about it getting too hot because its covered??

I have had success with hydrogen peroxide . I would dose 2ml for every 15g of water volume. The zoo's will close up for awhile but open bigger than before you dosed. You don't have to drip just pour in.

Thanks Andy! I read about peroxide on Advanced Aquarist. I might give that a shot but the author of the article stated that the use of UV should perform the same function of sterilizing the water. I haven't used my UV in a long time but I think I'm going to turn it on once the blackout is over.

I'm also running heavy Rowhophas and Carbon. Crossing my fingers...

I just finished the 72 hour blackout. The tank seems to look better but difficult to say for sure because I'm only running my moon lights at 8 percent intensity. I swapped out the carbon and rowophas over the weekend and turned my UV back on.

The article i read on advanced aquarist says to start doing water changes but in the book, "Algae A Problem Solver Guide, Julian Sprung suggests (page 69) "letting it run its course" and not doing any water changes for the duration of the bloom.

He also says (page 69) "Specific bacteria may also be used to control the Dinos" but he doesn't say exactly what bacteria that might be.

My ALK is currently at 10.5

Any suggestions?

Thanks!

Why no water changes ? I'm having some similar algae issues

I'm pretty sure the book I read said the same thing as Lenny that the fresh saltwater seems to aid in the spread. Don't remember why but I can look it up later today.

My advice is to get to it early. I feel that that is how I was able to get rid of it so effectively. Thankfully, it has not been back.
