I did a 30%
water change today and took a reading:
ammonia - almost zero (color somewhere between 0 and 0.25)
Nitrites - zero
Nitrates - 5
I had a thread where my previous readings (few days before this water change) were
Ammonia - 0.25
Nitrites - zero
Nitrates - 10
I'm a bit overstocked which may account for the ammonia and the water change probably brought the ammonia and
nitrate level down.
I began the tank June 21 so it hasn't been quite a month.
The collective wisdom of this forum is heartily appreciated.
