My girlfriend has a 2.5 gallon betta minibow tank that she just started up a few days ago. It has been pretty cloudy, I am not sure why? Also, her water level was low (about two inches from top) and I had her raise it up so you couldnt see the waterline from the outside, and ever since then the filter has been shooting out bubbles. Any reason it would be doing this? It is a Micro Whisper Internal Filter that came with the 2.5 minibow kit. Thanks for any help. The betta seems to be doing fine, just want to make the tank look nicer.
