Could somebody offer any thoughts on the strange behavior of my water readings.
I have been running my 28ukg for a couple of months now and up untill last week my readings were spot on except for low nitrate 0ppm, then this weekend i noticed a spike in ammonia(0.50ppm) so i added some ammo chips to my eheim and performed a 25% water change. At the same time as the ammonia spike my nitrate had shot up to 20ppm from 0 and nitrite was up to 0.25
Now some 2 days later to my relief i have retested and the levels have dropped to ammonia 0ppm,nitrite 0ppm and nitrate has stayed at 20ppm
The main thing that has got me slightly worried is that nothing has changed in the tank with no new fish etc so i can't even pin point why the change happened so suddenly or if infact if it will happen again.
Any thoughts or advice would be appriciated
