I have a 200 gallon tank that I've had setup and stable for a good year now with the same cichlids in it.Along with the 2 Aquaclear 500s and 2 Rena xp4s I already had on the tank,I decided to add a Rio 2500 powerhead inside for extra movement and an airpump underneath that so the bubbles get sucked up by the Rio and chopped up filling the tank with microbubbles.I cleaned out the Rio before using it so i know thats not the problem but my fish have started acting like they've lost their appetite and just aren't as active.Do you think these "microbubbles" or extra movement could be a little too much for them or it is simply a coincidence and something else is going on? Thanks for reading...
