What upsets / kills LPS, SPS, Mushrooms, Duncans, Cespitularia but not Zoas

[SteveZz]

I'm at a loss as to what is happening in my fathers tank. There's been a lot of death and destruction lately and I'm hoping to figure out why. I've since moved coral to my tank and the coral is slowly recovering.

Frogspawn closed and refuses to open much at all.
Candy cane receded dramatically.
Duncan will not open.
Zoas open everyday just fine.
Cespitularia looks okay but the polyps are closed.
GSP was opening
Mushrooms are closed.
Birds nest went downhill fast, some are recovering in my tank now, one died in that tank.
Monti's died.

Does anyone have a guess as to what might have caused this?

Ammonia 0
Nitrite 0
Nitrate 0
PH 7.8
Temp 76

^ all of the above measurements matched my tank exactly.

Running under LEDs in both cases as well.

Any thoughts would be appreciated, I'm glad I have them recovering in my tank but I'd like his tank to be back under control.

I should also add, we lost two shrimp and a hermit crab during this time as well.

is this a new tank set up?

if its an older tank, how long has it been set up for? any problems with coral growth in the past?

 

[SteveZz]

The tank with the problem is about 3 years old and we never had problems with coral growth.

The tank I'm moving things to was setup using water from what is now the problem tank and is only about 6 months old.

 

[Zoous]

It's possible that the corals released toxins that killed your other corals.

 

[SteveZz]

If that's the case wouldn't that slowly be removed through water changes? It's been over a month at this point.

We had also noticed the water becoming less clear. Do you think that could be some coral spawning / would that effect the other coral in the tank?

Hello there, I did not see you post anything about CA, alkalinity, Mg, salinity. Let's start from there first.

[SteveZz]

Salinity was 1.0205 on last check. I don't have the other tests at the moment.

 

[Samsreef]

Salinity should be in between 1.023-1.026. You should invest in alkalinity and ca test kit. That is most likely the problem.

[SteveZz]

Yea I'm working on bringing the salinity back up after we tested it. I'll work on those test kits thanks for the feedback.

 

[Zoous]

Is this a new or used tank?

 

[SteveZz]

It was a used tank from a friend of mine, and if copper if where you're headed he didn't use copper in it. Neither did I.

 

[Jazeel55]

Did you add anything new to tank any type of additive

 

[SteveZz]

Recent additions were birdsnest gsp and started using marine snow.

My tank was poisoned last year due to socks accidentally being poisoned by trapped LE soap in the rubber gasket of a front load washing machine killing all my sps and doing serious damage to my Lps. Zoas were not effected at all

 

[SteveZz]

That sounds awful. Sorry to hear that. I however only rinsed my filter media (possibly freshwater by accident once a while back) but I don't think that's the issue. It is however good info to have since it might just mean Zoas are extremely tolerant of everything and not to look at what kills everything but zoas as the question.

 

[BioMan]

Even if you dont have a test kit for Alk, Calcium & Magnesium,, constant water changes should always keep them at a decent level.

 

[SteveZz]

We do 5 gallons weekly on our 25 gallon tank.

 

[duke62]

Not saying it's the same exact issue but maybe your tank was accidentally poisoned another way

Yea I get your point, I'm now trying to think what if anything could've done this. How did you solve the problem?

 

[Jazeel55]

With tanks things just happen. My tank is doing great but all my acans decided to close up. Everything else is doing great. I can't figure it out. You got to just charge that to the game man!!!
