Rock salt, Kosher salt or aquarium salt (eg. API).

The nitrite is enough to explain the loss of the danio, anything above 0 is dangerous, 0.3 can be lethal.
 
I’ll try and get some. Any advice on the rams I started another thread for it but have watched the fish for 10 minutes and one of them is really struggling
 
I found some API aquarium salt so will get that. How much would I need to add, every water change and is this a temporary product or something I should always be adding to my aquariums?
 
The amount to use is explained in this link

It's a small amount, I was going to guess at about 6mg/l but Essjay's link should allow you to calculate the correct dose. Definitely temporary, once the cycle is established you won't need it.
 
Okay it mentioned normal salt should I give that a go?( it’s 100 percent salt nothing else) until I get some aquarium salt not sure how long it will take to get but will either order it with stuff for the rams or get some from Maidenhead tomorrow. All these problems are so stressful( it was so easy before I got more fish and the 180l) at least my Bristlenose gets on well with the rams and seems happy cleaning every inch of driftwood. Okay have just seen the what I believed injury come of. I think I must have worms then. I’ll get some worming things however on another forum they believe it’s just fish poo. Will my Bristlenose get infected with worms(will still do sort out the whole tank.) The poor guy being constantly bullied and worms that’s not fun.😢

I have read about how the ph affects what is dangerous to the fish and my ie somewhere between 7.5-7.9. So now less sure on the death of the danio.
 
There's a more reliable way to assess the 'harmfulness' of ammonia. I would ignore anything that says 80 ppm is 'alarm level' for nitrate as the upper safe limit is more like 20 ppm long term.


Our test kits measure ammonia and ammonium combined and the amount in each for depends on the pH (as you know) and temperature. There are on-line calculators to determine how much of that total ammonia is in the ammonia form.

Set salinity to zero, enter your ammonia tester reading, pH and temperature. You need the number in the 'NH3 concentration' box on the right.

Now look at the fish-in cycling part 2 sticky on here.

That gives an indication of how 'safe' the free ammonia from the calculator is.
 
I have 0 ammonia but thanks. I have been doing 30-40percent water changes to keep down nitrite and nitrate. The danios have shown any signs of nitrite poisoning they are using all areas of the tank but I might get some salt just in case. Thanks for the help guys.
