i'd used tap water to fill up my tank. recently purchased an ro/di unit, will be using it from this point on. My lights are on about 6 hours a day, which i dont think is too much. this is a brand new tank, so lighting and everything else is new.
thinking about doing a 20% water change this weekend. Do you think its too early for a water change? This is my second week of cycling.... my lr is cured and never had a spike in water levels. ammonia, nitrate and nitrite dropped a bit, since adding water to the tank.
ammonia = 0
nitrate = 0
nitrite = .5
ph = 8.4
