My circulation pump that I used in the tank broke, the tank then ran without any circulation for about a week, no visible issues I could see because of it. I then felt guilty and added a spare old circulation pump which after a month also broke. The tank then ran for a couple of weeks again without any circulation(again no negative effect on the pods). I thought at that stage that the water will probably start going "off" at some stage so just emptied it rather.
I dont have any large algae eaters anymore so dont really need it. I have a big sump so just throw any extra stuff in there.
