Upset tank

[jbadd99]

So, the backstory -

Cleaned my sump the other day, which includes a 20% overall water change. Changed out the sock, cleaned the skimmer, cleaned two sides of my glass. I previously had a Poly Filter in the sump, which was removed and only brown. Only thing new was I added Seachem Carbon in the return section of my sump.

Fast forward about 3-4 days. Some, but not all, of my zoas are, and have been, shriveled up. My candy cane is shriveled and looks to be dying. I also now have a MASSIVE outbreak of cyano at the front of my tank. The outbreak couldn't possible have any more flow on it without moving the sand all around.

Params as of last night:

Ph - 8.2
Alk - 3 meq/L
Amm - 0
trites - 0
trates - 2
Phos - .02
Calc - 400
Iodine .01
SG 1.024

Temp at 79.1 right now

All inverts are great. My RBTA is happy as can be. Frogspawn, green leather, and a couple other zoas look fine. I'm preparing another WC as we speak, just baffled as to the cause. Even checked for stray voltage with my multimeter.

I feed pellets once per evening. Frozen mysis 2x weekly. And the RBTA gets a silverside 2x weekly.

Tank is approaching a year old.

Any thoughts?

was your water change done with ro/di water? if so have you checked it for tds?

it happens.....I have gotton cyno when my phates were below 0.028 and trates below 0.5....It's a bacteria.....

scoop it out
chemi-clean
lights off
remove some sand
try vodka or other carbon dosing (could actually make it worse)

Figured I'd left something out somewhere.

I use RO/DI and check it before every fill. 0 coming into the mix can.



As the other poster said, I didn't notice anything until I added the carbon... and my trates have been around 10 before, but not recently.

But it's not really the cyano that has me concerned... at least not just</em> the cyano... the shriveled zoas is what really gets to me. They looked great last week.

Is it possible the disturbance of the filters released a bloom of bacteria? I had it in one spot and accidentally blew it away with a turkey baster and the following week it was everywhere.

 

[jbadd99]

Never had any before this past weeks cleaning and nothing new added to the tank in a month.

did you rinse your carbon in any way?

 

[jbadd99]

Alas, no. I'm still a n00b

But I did find out the hard way to rinse, just like the sand I didn't rinse.

I dunno if this has anything to do with it but it might have let loose some "fines" that aggravated the zoas, The candy canes are pretty hardy and most likely recover. Good luck bro I wish I had the answer you were looking for
