Hi, I am looking for a filter for my 2.5g betta tank.
A lot of people use AZOO Mignon Power Filter, which is powerful and saves room in the small tank. But some of them mentioned the current it generates might be too strong. Besides, it is not easy to find a AZOO Mignon Power Filter in local stores. I have been to PetSmart, Petco and Walmart, none of them carry it. So if I want it, I have to order it online which makes the cost go up.
Another choice is Whisper Internal Filter3i. It can be find in local stores. But it uses a air bump to push up the water instead of an engine. It says it is good for up to 3 gallons. Some of the reviews on the PetSmart website says it doesn't do a good job of cleaning the water, but some of them said it does.
Does anyone have experience with AZOO or Whisper? Which one do you think I should get?
Thanks a ton.
