Hi I need some advice please since getting my tank into my 3rd week
my test levels have been first week was ammonia 0 Nitrate 0 Nitrite 0 GH 125/ KH 50 PH 6.8
2nd week 0 / nitrate 10 / 0/ gh 125 kh 100
3rd week ammonia 0 nitrate 0 nitrite 0 GH 125 KH 270 PH 6.4
I have done my water change the only thing I've added is a oxygenating plant would this effect my water levels.

How are you adding waste ie ammonia to the tank? Which test kit are you using?

Hi Bertie I use King British safe guard de-chlorinator /K British 6 in 1 water test strips also plant food is tetra plant planta min.
What am I doing wrong i'm a little worried now and don't want to loose my fish.

How large is the tank & what fish are in there at what size?

The tank is 40 liters their 4 guppies 2 platies 3 tetra I think about 1ins also 3 zebra danio about 2ins
The tank has plants and for three week I have changed 25% of the water each week.

The king British strips are rubbish, showed 0 nitrate constantly on my tanks, I eventually purchased an Api kit and found the nitrates were off the chart on at least one of my tanks. I felt bad and humiliated, dump them and get a liquid based test kit.
