I have my betta by himself in a 10 gallon tank. He's been in there for a few weeks now. I'm using Prime and Stability since I'm too nervous to use TSS+ lol. Every time I test (which is frequently) it's always 0 across the board. I've been doing water changes once a week since I felt weird not doing any changes. Is the bioload just too small for the tank? How will I ever get this cycled? Should I not change his water until I see som ammonia?
