Keep loosing fish. Everything checks out

[Joe5688]

I've lost so far a loach, tiger barb, and a rainbow. The only thing i changed was adding 2 rocks into my tank 4-5 days ago. 2 days ago was my first loss. The next day another loss. I took the rocks out and did a 80% water change. No fish lost yesterday and now this morning i woke up to find a rainbow dead.

Ammo- 0
Nitrite- 0
Ph 7.5
Nitrate- 10

They show no signs of sickness. No spots or weird behavors. Only thing i can think of was maybe something was on the rock. some kind of chemical. I'm going to do another 80% water change today and clean out my filter.

Were the rocks from outside, or store bought rocks made for aquariums?

 

[JokerWx13]

+1 to George's question

 

[Hobgob]

Did you cleaning rocks? Also could anything have been on your hands when you put them in... I see you like working on cars so maybe some oil?

Haha It was in your profile, I saw it too!

Sounds like the rocks are the only reason for your losses. Your params look fine. Hopefully, the fish will stop dying on you

 

[Hobgob]

How dis you clean your hands? Did you use a scented soap? And ya your profile lol

 

[joy13]

Pesticides?

 

[Hobgob]

That's a good one seeing as it's a rather large aquarium. I would say what was introduced, it had to have been very toxic

 

[Joe5688]

Yeah I always wash my hands after work. I just sprayed hot water over the rocks in the sink for 30 seconds. I lost 2 harliquins last night. This is reply pissing me off

Are you testing for the Ammonia , Nitrate?

You may have some sort of bleach which got in somehow.

Test the water
And do a lot of partial water changes until things look better.

Check the first post. all my params are prefect.

I've done now 2 80% water changes in the past 4 days. Well see how it goes

 

[Fishy Aston]

You could have a outbreak of some sort of diesea?

Check to see if they all look normal

 

[Joe5688]

Just lost an angel. They all seem fine

 

[Joe5688]

One of my angels seems to have red spots on his head. Can't remember if its normal lol

Quick question. Should I add some carbon if it is some kind of chemical that was on the rocks?

 

[Lainey183]

I would add carbon.

I am also assuming you removed the rocks?

In the future I would reccomend boiling anything you add for like 2 hours.

Are they rocks with big pours? I am just trying to figure out how a rock could have so much of a chemical held up inside of it. It seems to be that by doing 2 80% water changes you should have eradicated anything that would have been harmful for the fish in the water.

The best I can say would be to add the carbon and keep doing water changes and vacuum the rocks or substrate super well.

Has the wood been in there a while?

 

[Joe5688]

Yeah the wood has been in there for like 3 Weeks. They started to die right after I added the rocks. I also brought home 4 gbrs that died before I added the rock. Maybe they had some kind of disease.
