Sorry for posting again about my water.....

Can you please tell me what the best amount of NO3 is, can I have the figure in mg/l please.

Can I have the best amounts of NO2 in mg/l as well please.

Can you please tell me the GH best amounts in dH.

And finally the KH amounts in dH.

I am worried about my water, and need to check things are Ok!

Thanks for all the help...

NO2 should always be 0

NO3 safe zone should be between 10-50ppm

Safe GH and KH is hard to determine without knowing your PH and what you are keeping. Generally lower GH and KH levels mean you have softer more acidic water and higher readings means you water is harder and more alkaline. Weather high or low GH and KH levels the safe range is pretty broad for most tropical fish.
