I've recently made a change from Aqueon Quietflows to AquaClears on my 20g and 10g tanks. I have another filter in both tanks and seeded the new AC filters with some media from the Quietflows, so I didn't see a mini-cycle since the change. The odd thing is, I'm seeing a substantial drop in nitrAte readings.
10g tank
past: 20ppm nitrAtes prior to weekly water change
present: 5ppm nitrAtes prior to weekly water change
that'w with two sparkling gouramis added during changeover!
20g tank
past: 30-35ppm nitrAtes prior to weekly water change
present: 20ppm nitrAtes prior to weekly water change
added 4 miniature swords during change
I always was suspicious of the biological filtration on the Quietflows, but couldn't imagine that dramatic a change to the nitrAte readings. Could there be another reason for this change?
