Can cyano kill frags

[Oshengems]

just curious if cyano can kill frags specially SPS frags of course not the early stages of cyano where you have 2-3 patches but a heavy population where is over your sand most of your rocks ? Just curious since it’s a bacteria

Following, I’m having the same provlem

 

[Oshengems]

I’m currently treating my tank with chemiclean, cyano seems to appear always around this time in the last 2 setups I have done over the past 3 years, I have been experiencing bleaching from over lighting my tank but I reduced my lighting and bleaching has continued, ive had 2 patches of cyano for most of the summer but over the past few weeks cyano took over idk if the spectral changed gave it the boost it needed. But last night as I was adding chemiclean this question came to mind. My sps in particular my acros the ones surrounded by cyano we’re loosing growns and my frags most bleached from the bottom up, And this Bleaching in my tank only had one thing in common and it was that bleaching never started on tips or middle of colonies they only and specifically started in the encrusted part and continued its way up but what I found weird was that bleaching would stop for a day or so and continue so a frag would take about 7-8-9 days to bleach completely

Another thing on my display i have Radions and on my sump I did a lil frag area with a Kessil A160 I had, I managed to clip the tip of most of the dying ones on my display and my sump is cyano free they are doing well in my sump it’s just strange I assumed it was the light but analyzing and thinking can cyano be a cause since it is a bacteria or can it be what I think it is and it’s actually dyno that I have and not cyano does chemiclean kill dyno ?

Cyanobacteria certainly can have adverse effects on coral. The question is what's causing conditions to favor this condition? Are you carbon dosing?

No dosing I have a “simple” reef
75g DT
20g Sump
~80lb sand
~110-120lb of LR some on my sump
Reed octopus skimmer
Mag return pump
MP40-MP10

I had cheato in my sump but removed it last year since my nitrates and phosphate was never dectected and reduced my skimming to 12 hours more on the dry side skim than wet

I was doing the ABCD 2.5ml-5ml a week of each and acropower once a week.

And ESV 2 parts

I believe it’s my poor summer maintenance that causes cyano in my tank since it’s happen 3 times during the end of the summer I haven’t done a water change in 3 months but will be doing a few big ones once this antibiotics kills most of the cyano i saw the dusty water this morning so I guessed it started doing what it does. So cyano can kill frags I hope this is the case since I can’t figure out what’s killing my acros I founded strange that Radions was bleaching my acros but my montis are instact every single one of them but they are colonies this is only happening to my frags (acros only) and Small acro colonies.

Currently waiting on my ICP results mailed them out about 3 days ago trying to figure this out

Hate to ask this, but what's you water pramameters like?

 

[Oshengems]

Np did some test last night before the chemiclean treatment.

Temp ~77-78
Salinity 1.025
Kh 9(elos)
Ca 400(elos)
Mag 1365(salifert bumping this to 1400)
Nitrates ~5(salifert)
Po4 .03(Hanna phosphate not phosphorus)
I2 .06(red sea)
K 450(salifert)
Fe 0(Red Sea I think I’m doing this one wrong)

I been feeding heavy to try to bring my nitrates up I always struggle with this I been considering dosing nitrates instead I read somewhere about nitrates helping reduce cyano not sure probably contributing to my cyano issue

 

[DSC reef]

Cyano is a fickle beast. In all our tanks we had to battle a little bit. It can smother corals but a simple turkey baster can blow it off the frags. On another note, our colors of acropora always seemed brighter when we had cyano

It can. I actually have too much N03, 40PPM and was P04 limited. I have no cyanobacteria. We know that dosing ethanol (vodka) can induce cyanobacteria out breaks if over dosed.


I suspect your over feeding is the culprit.

 

[Oshengems]

I been feeding 2 times pellets automated And 2 cubes of any of the following randomly, mysys, brine, frozen eggs, formula 2 and reef frenzy daily and 1 or 2 times a week I toss in a bit of reefroids or flakes just to keep 0-5 nitrates if I last 2 days only doing pellets straight to zero my nitrates

When I fought with cyano, it did kill coral tissue, I was naive and thought the cyano would not affect them. Please do not repeat my mistake.

So cyano can kill my frags I wonder if that’s the case in my tank atm frags in my sump do good so I’m assuming is not my water. I’ve had a few patches but they stay the same over months but summer came and I slacked I won’t lie, a few pieces died because I would last a few days without seeing my tank. But back at it again major maintenance this weekend

To clarify, cyano wont kill your coral buy being present in the tank but it can smother the coral if not blown off regularly.

Major case or just a few patches ? It was crossing over to my sand that’s my que for chemiclean

Yeah I kinda figured that’s what you meant ive had patches here and there with my acros thriving but I avoid blowing it scare it might spread but I had read before on older post that it doesn’t kill corals they can fight off or at least defend their turf vs cyano

 

[DSC reef]

Typically I would crank the gyre up to max and go crazy with a baster or a powerhead and let the sock catch the debris or manually remove via siphon during water changes.

 

[Oshengems]

I tried to remove the big big chunks yesterday but then gave up and tossed in some Medicine

IMO cyano will kill coral...even mushrooms. I have struggled with it for years. Even with a ULNS. My go to quick fix has always been chemiclean. Always works with no issues. Carbon dosing with alcohol always initiated another outbreak. Now I am carbon dosing with vinegar. NO CYANO. My tank "looks" much "cleaner". I will always employ this method of nutrient export. Not saying this is the way you must do things. But worth considering.
