Fish dropping one by one, coral are fine.

[Sqeezle]

120 gallon system
-60 gallon tank
-10 gallon side tank(anemones, acans etc..)
-50g sump
1 1/2 system

i run 2 different skimmers. one recently stopped working. so i have been only using one for quiet some time(maybe a month?). that skimmer is rating for 80 gallons at the most.

about a week ago (dec 8ish) my blue jaw was acting funny, wouldn't come out, wouldn't eat all day. A few days had past i did a water change. ( i make my own salt water, dnd H2 ocean). i haven't had any problems with this salt before and works perfect. I added fish keeper and melafix marine (antibacterial fish and coral remedy). The day after i did the water change he was dead. the day after my flame angel was dead, the day after that my clown fish in my enemone tank was dead.. then today dec 15 i did a 55 gallon water change, cleaned my sump. my flasher wrasse was dead during the water change. now my blue hippo is acting funny wen i got home tonight.. my skimmer wont skim, because the fish keeper and melafix marine are still in the system and it irritates my skimmer and over flows


before my 55gallon water change my..
phosphates - 0
nitrates - 100 ( i will test my nitrates tomorrow)

2 reactors -
purigen and carbon. i recently just added the carbon reactor after my blue jaw was sick.

and as said in the title, corals are all fine.

I'm pretty sure it may be the nitrates.

 

[Sqeezle]

wouldnt it effect my coral though?

 

[janiners305]

Depends on the coral some like nitrates. But for sure high nitrates will kill fish I would get the nitrates down as low as possible. Water changes and maybe setup a bio pellet reactor..

Arent coral more effected by nitrates then fish?

 

[janiners305]

They are but sometimes can take longer to show symptoms .. Phospates usually affect corals more

How's your pH/Alk? Your nitrates level is really high and how many fish do you have in the tank?

Have u got anything new lately. Sounds like a Parasite or marine velvet.

 

[Emac909]

Nitrates would effect corals first not fish. Specially sps.

Maybe temp swings? but still corals would b effected too. How about o2 levels? It's been cold the last few weeks have u opened any house windows? Sometimes if your house is closed up for long periods co2 builds up in the house and your tank won't get fresh o2. Did the fish look like they where gaping for air?

Some people have no clue what there talking about and start throughing the first thought out or what other people have told them. Sometime large water changes will do more damage then good. I would say run some carbon to see if it helps.

 

[Emac909]

Also what carbon r u using?

 

[JasonG]

I agree with mac, 100 nitrate is high but not high enough to kill your fish off one by one over a few days. Are the fish showing any physical symptoms other that acting weird? Look closely at them, check for spots, discoloration, tattered fins, mucous, etc.

 

[reefes pieces]

+1 to eMac when was the last fish introduced? Sounds like velvet to me

 

[Clifford]

Where do you get your Rodi from? The clownfish that died was he in another tank? Are you using activated carbon?

 

[wickedfish]

Hmmmm. What and when was then last fish you added? Also where did you acquire it from? What made you add an anti fungal to your tank? Melafix is pretty harsh.

If your first fish has a fungal disease IME they usually pass it on and pretty much all fish soon die after that. I has an angelfish wipe out 14 fish in a matter of weeks. Only fish to make it, Kobe the purple tang. Fungals and velvet are a death sentence.

+1 to what everone is saying.

Im rebuilding from Black ich. I thought I had velvet too. But I showed adrock these photos and he said its black ich. It wiped out all but 4 of my fish (I had 17). They died within 1 week of the first one. The fishes that had it were constantly flashing against the rocks, or stayed in front of the powerheads only.
