Dinoflagellates.

How long did you overfeed for ?

Over fed for 4-5 days. Now I feed about 1 cube every two days + auto feeder running twice per day.

I think the best way to do it is order a cheapo microscope off amazon and monitor the population of the beneficial creatures. When dinos were present, there was not a single other creature to be seen.

I also started skimming and removed the filter socks as they were trapping thousands of tiny creatures who appear to be constantly munching on detritus.

Ive read through nearly this entire thread. I currently have Dinos but they arent nearly to the porportions you guys have had them. Mine will take 4 or 5 days to really get annoying to coral and its mostly the frags. I have SPS that are still alive and growing (albiet slow) i have 2 RBTA and 2 RFAs a rabbitfish, starry blenny, urchin, 2 clowns, and 2 shrimp gobies. My CUC isnt dying and i havent had a snail die off like others have mentioned. I do believe i lost a kole tang to this stuff before i knew it was dinos but at the same time there is no way for me to know as it was pretty new to the tank.

Tank info, Red sea reefer 250 (65 gallon system). Used about 15ish lbs of "live" rock from a tank i had set up and running for 6 months. also added about 25 lbs of dry pukani rock a month after setup of the tank. The tank has only been running since october, used carribsea argonite sand. I run rox.8 carbon and use a vertex omega 150 skimmer (way oversized.)

Im not certain but im pretty sure ive had a slight amount of this stuff since end of november, and it took off after i removed a large amount of bryopsis turf algea and peroxide scrubbed a large chunk of the rock.

So far ive tried a ~3 day somewhat blackout.. not total, i didnt cover the tank or anything and i had the lights on for ~45 minutes each night so i could feed the fish and the anemones. (nems werent happy about no light) i dosed 7ml peroxide morning and night during this time and a couple days after. I went 2 weeks without seeing dinos after doing this.

Then my skimmer went offline because i mounted frags with epoxy (took 1.5 weeks and 20 gallons of new water and its JUST starting to work again) and i noticed them starting to return. My corals and nems i dont think will last another 3 day blackout and since it didnt solve the problem im not sure i want to try it again anyways.







Now it kind of looks like a type of cyano, except in the morning its nearly all gone and by noon its back again. The more i let it go the stringier it gets, but it also grows on the glass and fragrack. I am trying to get access to a microscope to identify. What are your guys's thoughts?
 
EDIT: This is what it looked like prior to the blackout and h2o2, it is MUCH less than this now. Ill try to take pictures tonight, i just wanted to upload what it looks like when its bad.
 
diatoms or dinos?

diatoms or dinos?

Are these diatoms or dinos?

Wondering if I should add bio balls in back of biocube to allow little creatures to multiply and breed back there? Right now, there isn't anything. Advice?
 
Would you guys say mine looks like ostreopsis or something else?

Your pic didn't show up!

@Billy yeah I'm still not sure. It looks like dinos in some places and cyano in others. That hair on the rocks doesn't quite look like dinos but I don't know what it could be. Putting bioballs back in won't hurt, but they may eventually raise nitrates. Are you dosing phyto? I like your idea of transplants from your new tank (what a steal! why can't I find deals like that?) a lot better than bleaching your system.

@Manny did you check Pants' website? Good video, they have the really classic Ostreopsis shape but O. have this odd behaviour where they spin like someone nailed one of their feet to the floor. I don't think I see that.

@Monkey Nope, no green dinos. Looks like cyano, does it come off in big patches?

hth

No i havent seen Pants' website..
Mind linking me to it?
Also they do spin in a big circle..kinda like a clock.
 
The green growth looks more like cyanobacteria or the beginnings of coralline to me. Cyanobacteria will come off the rock to a very light touch.
 
Does the forum not me post pics using photobucket? is there a different way to do it? I literally joined to be a part of this thread lol

Your first post in this thread doesn't have any link to a picture. You might have accidentally edited it out? Try posting it again. Photobucket should be fine. If you can't get it to show up inline just post a link to the picture on Photobucket.
