Sorry, for not getting back straight away but internet problems :(
Its fairly small tank for two fantails, around 40l / I try to change it within next 2 to 3 mouths/ I do have a filter and air pump.
Readings are from tonight:
Ammonia - 0ppm
Nitrite - 0.50ppm
Nitrate - I can?t read it properly but is between 40 or 80
Is just split as far as I can see no fin rot or any kind of fungus.
On the day, I post that I have problems i change 40-50% water change and treat water properly before putting it back to tank.
Any suggestion how I can help her?
Thanks in advance
