So we've had Twilight for a week. The tank he's in was cycled when its prior occupant passed away, and had been sitting half full of water for about a month. My bf rinsed it out and replaced the filter before we introduced Twilight and we put freshly conditioned water in there. The biowheel and gravel is the same that was in there before, just rinsed off. And the biowheel had dried out due to the low water level while the tank was empty of fish.
I was expecting to have to re-cycle the tank, so I did a partial water change midweek and another partial water change today (about 50% of the 3 gallon tank). Today I tested the water and it was practically perfect, except for the ph. The ph was hard to figure, it looks like it's between the high and low range tests, so 7.4-7.6? Everything else was zero. I'm very skeptical about that, how are near perfect water parameters possible already? Are those bacteria really hardy enough to survive a month of neglect plus rinsing?
Or could my test have expired? It's the API master test kit with the bottles of liquid.
Thanks :) Oh and Twilight seems to be ok, he's eating 2-4 pellets in the morning/evening and swimming around. He's sleeping/resting at the surface above the filter intake a lot, but maybe he's just relaxing? Water temp is a consistent 78F.
