I noticed that the basket on one of my aquaclear filters had popped up leaving some of the media pretty dry. The media wasn't full either. I think that the notch in the basket was not catching with the side impeller plastic part, so I just removed the basket entirely. I do have some other used aquaclears that didn't come with a basket, and they work fine as far as I know. Do you think the basket only for removing media quickly, or do you think it leaves a bit of a gap in the media cavity for water to circulate. Appreciate your thoughts. Thanks!
