How do I stop my filter current as I feel like its to strong I have a whisper tetra filter my neon tetra and my betta have to swim alittle harder just to get to the other side of my tank any ideas on how to fix this current issue
Some fish wont like it. Does your filter have an adjustable outlet? Most of the popular ones nowadays do, you could potentially throttle it back slightly if it is too large for your tank.
