265 gallon project
- Thread starter niloc16
- Start date
dont know what is happening lately, i have what i think is cyano but it is extremely dark brown almost black in color. and when you syphon it off it comes off in sheets. its a major pain in the butt. i have test everything i can and everything is good, flow is definitely not an issue i'm assuming its due for bulb changes. the bulbs are only 9 months old and i was planning on changing them at 10 months but i will do it early and hopefully it helps.
anyone have ideas what might cause the outbreak?

i use a dart for the return pump. i had a hammerhead pump for my closed loop system but i removed the closed loop after a month. it was too noisy and the benefits were not that great, so after i removed it i replaced it with 3 tunze 6100s mounted on wavyseas. now that i have done that i would never go back.

I have a 150 gal with good flow and have the same dark brown or black sheet growth. I run a SE 250w MH so I do not think it is related to the bulb. I believe mine came in on some live rock and is now spreading. I would love to hear if you find any info on it as I have not been able to.

What did you test and what were the readings?
How much do you feed and how often?
What is your fish load?
This will help in figuring out what the problems are.
nitrates unreadable.
ph 8
po4 .05 this has always read this amount
ca 1425
kh 10
i feed once a day varied stuff. one day 6 cubes frozen, another flakes, nori, etc. sometimes i feed twice a day once in am and one in pm.
i have 21 fish, 5 small to med tangs, rest are small to med fish like chromis, wrasse, anthias etc.
weekly water changed is IO, top with ro/di and it only starting to show maybe a month ago. it has been running for year

I just did a search for Cynobacteria and the concensus is that it's caused by too high Nitrate and or Phosphate. Try a search yourself and see if anything sticks out at you.
When I asked for your params, I just knew you would come back with high nitrate or phosphate or that you were feeding too much. There must be a reason for low test and Cyno. Something isn't adding up.
Good luck and let us know how it turns out.

thanks for the advice gary, much appreciated. but i figure po4 of .05 wasnt extremely high and by reading alot of other tank journals is quite average but maybe i'm wrong. nitrates were unreadable and i checked them again last night and same thing, nothing. i'll definitely let you guys know if i figure this bugger out
well i think i may have finally kicked the dinos. dont know what 1 thing killed it but i tried alot of different things. heres a list
replaced ro/di filters twice
cleaned all pumps and redirected wavyseas
more water changes/ less water changes
replaced MH bulbs
cut feeding down to every 3 or 4th day
turned CA reactor off
tested any water associated with tank
ran lots of carbon
excessive sandbed syphoning and cleaning rocks
wet skimming
chemipure
the final draw was an 8 day blackout which killed it off finally. but the dino spread was so big that when it died off it completely polluted the tank and killed alot of corals and caused a big chain reaction of death.
but so far it has not returned. most of the corals really really browned out but now they are starting to color up again. all LPS but 2 frogspawns died. we'll see how it goes. i really hope it doesnt come back though

i'm finally starting to enjoy looking at the tank again. i spent about 2 hours yesterday tweaking stuff and scraping coralline and what not and took some pics today. i kind of wish i had taken some pics when the dinos were rampant to compare but anyway here is a couple for ya. i know it is kind of drab right now but slowly the color is coming back

Niloc,
Super Tank. Of course, you know I've been following your thread since Day 1. You've provided great advice too. I am still taking things really, really slow (probably too slow) with my 265g. The only livestock I have are snails, (1) coral banded shrimp, (2) acropora frags, (1) galaxea & (1) frag of green star polyps I've had for almost 2 years in another tank. No fish. I did have 3 small green chromis & 1 Salfin Tang, but they died within 1 day. I don't know why, as my parameters were all great. Seems as if the acropora and others would've died. However, I have experienced an algae bloom. This came after the cyano cycle from a new tank. So, with this being said, I think you may be okay. I guess things just happens.
