I'm new to the forum, but I'm not new to fish keeping. But this one has me at a loss.
We got our daughter a 2.5 gallon fish tank for a Betta on Christmas.
We got the gravel, and some anacharis and one decoration and things were going great.
But this Nitrogen cycle has me so confused.
Using the Master test kit, these are my results
Nitrite-off the chart
Ammonia is .25 coming out of the tap, which bothers me, but it can be dealt with. I have Prime to use.
pH has been stable, the plants are growing.
The Betta is completely fine. He eats out of your hand and swims around his tank, and his color is good. He's even built a bubble nest, But the Nitrites have been off the scale now for over two weeks.
We do almost complete water changes and I treat the water before adding it to the tank, and then I also add extra prime to lock down any Nitrite left in the tank.
But 24 hours later, the Nitrite is off the chart.
I know the tank is cycling I was hoping the plants would have helped with this issue, but there has to be something else going on that I'm not thinking of.
Tank has a whisper internal filter and heater.
This is the smallest tank I've ever tried to cycle. I'd appreciate any advice or insight.
