Hi everybody, I am new here having just returned to the hobby after a break of five years.
Anyway, my question is, what is a safe level of nitrate (NO3) for Cardinal Tetras before having to do a water change? Also, will NO3 levels continue to rise with the absence of plants or can they stabilise?
At the moment I have what I believe is a semi-cycled tank. Total ammonia is 0.25mg/l, NO2 is 0, NO3 is 10ppm. pH 7.0 and temp is 27 - 28c.
