265 gallon setup

did this cyano brake-out occur after your last coral addition.
I had a serious cyano problem after adding 3 colonies from HR last shipment.
I haven't even seen any in 2 years and I attribute it to that.It seemed to be a stronger strain. Probably a hitch hiker IMO

no it didnt happen after the last addition. to be honest i dont know what brought it on. its been slowly building for 2 months and now its a killer.

man, that sucks. pat, pat. it happens to the best of us.

I'm really very sorry to hear this.

I feel a tinge of guilt because I said I thought the corals could withstand a 2 day blackout. I really don't know what to say. I'm sorry.

I know about the dead coral thing. I can at least share a little of your pain there (different reasons - and still ongoing I've given up on the tank in question - it's beyond fixing).

I really hope you get on top of this soon. I know the frustration of dinos, I had it twice, and nearly quit the hobby 100% both times. It's very demoralizing. I hope it resolves soon.

good god tony you dont need apologize. its not your fault at all. but thanks for the input though

Maybe you've considered this...Keep siphoning it away from the corals, rock etc...but leave it alone where you can stand to leave it (on the sand?).

I'm thinking that whatever nutrient it's living on..maybe it will use it up if allowed to grow.

If large water changes haven't helped...do the opposite. Back off on your water changes....see if it gets worse or better.

In my previous life, I knocked it out with a new skimmer. On my new tank, it just went away in exchange for hair algae...which is the lesser of two evils.

that may be an idea because today is the 2nd day i have turned lights on for 4 hours to help the corals a bit and it does not seem to be coming back on the rocks and stuff but is takiing off on the sand.

Without reading previous posts you should give chemiclean a try.It solved my problems and never had a prob after.

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 actually enjoying looking into the tank again so i couldnt refuse taking a couple tank shots. i know its pretty drab looking right now with stuff browned up but slowly the color is coming back. i kind of wish i had taken pics when the dinos overrun everything to compare to now.
