Hey all. I have a tank I'm fish-in cycling, not by personal preference but took over as caretaker of a friend's betta when they moved back in early March. It's been 5 weeks come this weekend, and the tank still isn't cycled. It's a 5.5 gallon, our pH out here is 7.6. For two weeks, I had almost no ammonia readings with the betta in the tank, but did a weekly water change anyway. 2 weeks ago, I had my first ammonia reading. I've been doing small 15-20% water changes daily to every other day since the ammonia was building up and fluctuating between 0-.25 ppm, then eventually .50 and climbing so I figured okay, good sign. Then this Monday comes along, and I get my first hint of nitrites! Somewhere between .25 and .50, leaning towards .50 ppm. I did a small, maybe 15% water change that day because I was going to be gone overnight and wanted the betta to be safe just in case a spike happened overnight. Since then, since Monday, I've had no nitrite readings whatsoever. All testing is done via instructions from the API liquid testing kits. I did put in Prime conditioner on Tuesday, yesterday, which is the only variable since then, to keep the betta safe in the midst of the cycle kicking in. But now I'm at this point for the last two days where I'm getting almost nothing---0 ammonia ((maybe a very very light .25?)), 0 nitrites, 0 nitrates. Was absolutely positive there was no way that that small of a water change removed almost .50 ppm of nitrites. I'm not sure if this is because of Prime, or if I managed to somehow ruin 5 weeks worth of progress? I'm not sure what's going on with the tank. This is only my second cycle, so any help would be great. I wanted to throw Tetra SafeStart in there, but the betta has had fin rot in the past and I was worried that being unable to use Prime, the ammonia/nitrite spikes might affect him during the cycle. Any input would be great, thanks!!
