Lost some angelfish trying to figure out if my water levels are ok

[batson325]

I just lost a Congo tetra and took a picture to post and make sure that you guys still think its the slime coat. Just in case there's something else I should do to prevent more losses.

I'd do a water change. 50%+

[eklikewhoa]

I wouldn't do a water change just yet with the water source being the problem.

Make sure you're using a good dechlor like seachem safe/prime or kordon's amquel+plus. Dose according to the label for ammonia/chloramine.

The Ammonis is real bad. That alone is enough to kill your fish.
If you are salting the tank every water change and doing 25% water changes. You may have to much salt as well. Salt doesn't just go away. I would do 90% water change.

if the water source is the culprit of the ammonia readings this should be addressed first.
Op stated the tank has been set up for 6m now but there was a new addition of 20 fish with some dieing...

That would be Chloramine which would be giving the ammonia reading if this is the case.

Agreed, but ammonia/chlorine in the tap is easily solved- the water conditioner should be locking up any ammonia, correct? Resulting in a reading showing ammonia present which is actually not toxic- Chlorine the same, prime should lock it up, right? The reading of ammonia in this case is false and should be disregarded as I understand it.
.... But OP's nitrate levels are high enough to cause problems, regardless, which IMO indicates a bacteria colony issue with an influx of occupants like he describes. I can't come up with a reason otherwise for nitrates to be that high if the tank is seasoned, + the W/C schedule he describes... Water changes need to happen to bring those levels down, if not they're only going to go up.

Not to belabor the point, but OP- you've added about 55 fish staggered over the last 2 weeks? In a 210 that shouldn't be that big of an issue, depending- How long between when you took the malawi/peacocks out and when you added the new fish? If there was a lag, it's possible some of the bacteria colony started to die off due to lack of food. And what was the bioload like before? How many fish/sizes? Recently changed any filters, media, etc?

I went over to fish gallery to see Don and showed him some pictures. He seemed to know what is going on and sold me furan-2. I'm doing a 50% water change, then I'm going to add the furan. I'll let you know how it works. Thanks for all the help.

Hope it works out, good luck and definitely keep us updated.

does (Del Destino) 100% natural sea salt work?

[Ogrodii]

anybody?

[troy tucker]

Yes it will work if that all you have.

yeah all I have right now
