I am moving my female betta to a 5 gallon tank soon. (She's in a 1.5 now but it's way too small.) I'm worried that it will be hard to cycle a 5 gallon tank since it's still pretty small. Also, the cycle would be lost after every filter change. I have some ammo chips in her 1 gallon to keep the ammonia down and they work great. The tank has been at 0 ammonia since I added them and I recharge them every 5 days. The ammo chips are also very cheap since I just reuse them over and over.
I don't see any use in cycling the 5 gallon. It would be hard to maintain and the cycle could die after every filter change. What are the benefits of cycling the 5 gallon? Is there any reason why cycling might be better than ammo chips?
Also, I have a 20 gallon which I'm going to cycle, but now I'm just thinking about ammo chips since it's faster. Should I cycle to 20 since it's bigger?
