I'm new to fishkeeping. I have a male Betta in a five-gallon tank with about four gallons of water in it. I've had it going for a week today. I tested my water this morning: ammonia 0.25 nitrite 0.50 nitrate 10.0 pH 8.2 temp 80f* Now, shortly after testing, I conveniently sprained my knee while grocery shopping. (Add that to the list of ACL risk factors.) If a water change is indicated, I can't do it. What does this tell me about where my tank is in the nitrogen cycle? Please tell me how to treat the water, if necessary, and offer whatever other advice you'd care to. Thanks! * I guess this is a little warm, but I have a small, pre-set heater and there's no way to adjust it.
