Hi, around feeding time, I shut off my filter. I do this so that theres no movement in the water and the fish have a chance to eat as much as they can without some of it getting sucked into the filter. Also, it keeps the tank cleaner because you dont got food shooting around all over. I usually unplug it, then I leave it off for about 20 mins. I do this to give the fish time to do clean up. Then I just put it back on. Do you think turning it off anf on like that will cause problems to the filter? Ive done this for a few weeks but jsut stopped a few days ago because I had the thought about maybe doing harm to the filter. What do you guys think?
