Media Basket - Single tray with foam

I guess I did not look at the picture well enough before purchase. I was expecting tightening screws on the media basket similar to what the filter sock holder has. The media basket floats a little with the foam installed and moves so it does not stay flush against the weir causing some water to bypass the foam.

Does not fit.

Fiji cube if you guys are reading this please see the email I sent. This thing doesn’t fit or work well in my 20g peninsula, I didn’t wait for a month or so for this.
