So, this is my basic tank setup: a large Kritter Keeper that holds 2.5+ gal of water, a Tetra Whisper3i Filter, and a Cascade 7-watt heater. I didnt cycle it before I got my fishy :X
I've had my betta for about 6 months now, and she's been doing well with weekly 100% water changes.
Recently, I've heard that this is too much water to be changing every week. Is that true? If so, how and when should I do partial water changes?
Also, is there any chance of a cycle establishing itself if O never change the filter media or kill the bacteria in the gravel?
