I just came home to a mess. Blue tang (super healthy) found dead, Clown fish labored breathing, inverts fine, coral fine, and Tomini Tang fine but swimming into powerhead which is abnormal.

The only thing I changed schedule wise was the addition of Sea Klear phosphate remover dose which was 4 drops (not the first time ive used it) and i fed thawed frozen that I left in the fridge.

The symptoms are exhibiting Ammonia poisoning, but I've had the tank set up for 4 months. My tank is 180 gallons.

Any insight or ideas?

I am heating up a second tank now, I've done a 50% water change and added sea chem prime in case of ammonia ( i dont keep tests for ammonia )

salinity 1.026
temp 80
nitrate 4
phos .13 before i dosed this morning
alk 8.9
 
Oxygen deprivation by the sounds of it. The fish swim into the powerhead to try to pass more water through their gills.
 
While the initial sentence sounds like velvet...BUT

Then you mentioned dosing Lanthanum Chloride. Fish, especially tangs struggling to breath with this is not unheard of.

Do you dose into a fine filter sock or such?

Possibility that it was lanthanum poisioning.
 
i did not dose into a fine filter sock. Hanging my head in shame.
 
More curious how much phosphate went down from .13. Insoluble lanthanum not very toxic at all. It would be too much soluble salt at once that could do it.
 
Its really a matter of how fast its dosed. If that is the reason.
I dosed 4 drops into the sump before i left for the day. Felt good about the 2 drop test from last week.

So now I've potentially killed 2 fish to lower phosphate...

Makes me want to give up :/
 
Thats what i used because i did a test last week using 2 drops to lower it by .05
I’m just saying, it’s hard for me to believe that four drops of anything in 180 gallons would kill anything. I mean, if it’s that toxic, how does anyone ever use it?
 
That's my thoughts exactly.

.15 phos 10/14
dosed 2 drops

.13 phos 10/16
dosed 4 drops

Dead fish 10/16
 
I don't know the concentration of this brand so I cant say for sure. 4 drops does seem very little though. Couldn't rule out ammonia it was not tested for. If for example that 4 drops knocked phosphate way below .13 this could indicate it was possible. Are you running any controllers that might have orp readings? That could rule out oxygen issues.

I am not :/

I am fairly middle of the road tech on the testing side with hannah checkers

Well you are supposed to filter it out. So people dose into a small micron filter sock (5-10?) or such. The lower the PO4 the more toxic it is... since some of the La may not bind to PO4. A little goes a long way.

Tangs are high oxygen demanding fish guessing that is why they get hit the hardest. My guess is the fine particles get in their gills and suffocate them.

The clown is labored breathing but will swim, resting mostly, i hope the water change helps.

very bummed
 
Thanks to all. Wondering if there’s anything else i could do for the clown .
