Hi again everyone.
Disaster is striking. Starting to lose all types of fish in my tank. All are showing signs of ammonia poisoning but I've checked all my levels and all is good. My ammonia has never shown a true yellow just a very slight green tint. I have two test kits and both have always shown the same.
Nitrite 0
Nitrate 30. My nitrate is always a little higher as it that way through my tap. No pH swing that's stable.
This is affecting everything from rams to tetras. They all have slightly red gills and are sucking water in like crazy. The only one that seems nearly OK is the dwarf gourami. Possibly I'm thinking due to his labyrinth gland. Oh and the bristle nose.
Anyone had any similar problems and found any info. Anything will help.

Just a bit more info.
It's a 125l with an external filter and an internal filter rated for upto 100l that is also used to disturb surface of water.
It's planted with anubias barteri and nana, plus a red lily.

First port of call is to do a very large water change. 80% or more. Report back once that is done. This should always be the first step if nothing else has changes recently. Have a think and let us know?

Could any chemicals have got into the tank? Anything from a child pouring a bottle of something in, to using an aerosol, glass cleaner on the tank, air freshener, paint fumes etc in the same room?

Hi @hilly
Could you please let us know which test kit you are using for ammonia, nitrite and nitrate? And, are they within their expiry dates? Also, would you happen to know the water GH, KH and temperature? How did you cycle the tank and was that done recently? That'll do for the moment.

One more question - sorry, plus a tip for finding out the GH and KH.
Do a test of your tap water and let us know if the ammonia reading is any different there from the tank water.
If you don't know your GH and KH, check your water company website, input your postcode, and let us know what the hardness levels are for CaCO3 and German degrees hardness.
