Help dinos?

[dk638]

My tank is 3 months old, it was a semi transfer, I moved some fish and about 15 lbs of live rock from a nano to this 150 gallon. I used about 150 lbs of dry rock from reefrocks.net. So long story but what the heck is this stuff? I'm hoping not dinos but the small amount of corals I have are dying and this stuff ain't! Lol

Any advice on how to kill it? I've been dosing h2o2 for about 6 days. Looks a little lighter in color now but still a lot of it.
Ughhhh

Lights out for 72 hours. Make sure you have a good skimmer, and do a water change after. I say this as when they die, they will foul the tank.

I dont think it's Dino's, well not the normal ones.
I had them in my tank, I increased my N/P and it went away and corals came back to life.
Just a case off to low nutritions

ive got this as well, problem is i have HIGH nitrates and they just arn't dropping they jumped from 0 to 25-50 over night when these popped up! not only that my phos is 0.008 :/

I'm on first day of blackout now will see what happens in 3-4 days. bit scared for my corals though

 

[IAmNotGr33n]

Yeah my problem was the same, N=25-30 and P=0,00
And nitrate cant go down, when you're phosphate limmited, i dosed som potasium-phosphate to my system and slowly my nitrate went down.

If your N and P is low, try turning off the skimmer by day, and only having it on by night.

Blackout worked for me. Literally covered my tank in card board and cut a small hole for feeding fish. 72 hours later all gone.

I had to do all of the above. black out for 96 hours, raise PH to 8.5-8.6, does H202 and siphon any remnants out. Took a while but the tank settled back down.

Also, check your lights. if you are using CFL they may need to be replaced. I replaced my CFL sump lights with PAR 30 LED bulbs and nuisance algae almost completely disappeared in the sump.

Almost all gone. One day my rodi stopped producing water. So I pulled it apart and all filters were a mess. Replaced membrane and all filters did some big water changed and it started clearing up. Can't seem to fully eradicate it though, there is still a little hanging around but corals look much better
